The answer is 32 electrons.
Answer:
32 electrons are the maximum electrons found in the N shell.
Explanation:
According to the periodic table, Maximum number of electrons in any energy level of known element is 32 which is found in N shell.
Each shell can contain fixed number of electrons. The first shell is the K shell that holds two electrons, the second shell that is L shell which holds eight electrons(2+6), The third shell is M shell which holds 18 electrons(2+6+10), and the fourth shell is N shell which holds the maximum number of electrons that is thirty two(2+6+10+14) electrons. The general formula is [tex]2n^{2}[/tex] electrons.
The outermost shell is called the valence shell and the electrons present in these shell are called valence electrons. Each shell consists of one or more subshells, and each subshell consists of one or more atomic orbitals.
Consider the location of barium, chlorine, iodine, and strontium on the periodic table. Electronegativities Which type of atom has the strongest attraction for electrons in bond formation? barium (Ba) chlorine (Cl) iodine (I) strontium (Sr)
Answer: The correct answer is Chlorine (Cl).
Explanation: Electronegativity is the property of an element to attract the shared pair of electron towards itself. In a periodic table, the electronegativity increases as we move from left to right and it decreases as we move from top to bottom.
The location of the given elements are:
Barium (Ba): It belongs to Group 2 and Period 6 of the periodic table.
Chlorine (Cl): It belongs to Group 17 and Period 3 of the periodic table.
Iodine (I): It belongs to Group 17 and Period 5 of the periodic table.
Strontium (Sr): It belongs to Group 2 and Period 5 of the periodic table.
From the above information, Chlorine belongs to the lowest period and greatest group number. Hence, it has the highest electronegativity and will attract the shared pair of electron towards itself strongly.
Therefore, the correct answer is Chlorine (Cl).
The more right you are and the more up you are, the stronger the connection.
Start by going left to right. The two furthest are Iodine and Chlorine (so barium and strontium are eliminated). Then look at that column vertically. Chlorine is further up, so that is your answer.
how many moles of aluminum metal are needed to produce 3.33 moles of aluminum chloride?
To produce 3.33 moles of aluminium chloride, you would need 3.33 moles of aluminium metal.
Explanation:To find the number of moles of aluminium metal needed to produce 3.33 moles of aluminium chloride, we need to use the stoichiometry of the balanced chemical equation.
From the equation: [tex]2AlCl3 + 3H2O(l) -- Al2O3 + 6HCl(g[/tex],
we can see that 2 moles of AlCl3 are produced from 2 moles of aluminium.
Therefore, in order to produce 3.33 moles of AlCl3, we would need 3.33 moles of aluminium.
3.33 moles of aluminum metal are needed to produce 3.33 moles of aluminum chloride.
To determine how many moles of aluminum metal are needed to produce 3.33 moles of aluminum chloride, we need to look at the balanced chemical equation for the reaction between aluminum and chlorine:
[tex]\[ 2Al + 3Cl_2 \rightarrow 2AlCl_3 \][/tex]
From the balanced equation, we see that 2 moles of aluminum (Al) produce 2 moles of aluminum chloride (AlCl₃). This means there is a 1:1 molar ratio between aluminum and aluminum chloride in the reaction.
Given that we need to produce 3.33 moles of aluminum chloride (AlCl₃), we can use the 1:1 ratio to find the moles of aluminum needed:
[tex]\[ \text{Moles of Al needed} = \text{Moles of AlCl}_3 \][/tex]
Therefore:
[tex]\[ \text{Moles of Al needed} = 3.33 \text{ moles of AlCl}_3 \][/tex]
So, 3.33 moles of aluminum metal are needed to produce 3.33 moles of aluminum chloride.
The titration curve below represents a titration of HCI by NaOH.
The titration curves in comparing the titration of strong acids and bases with the titration of weak acids with strong bases. It is a high school level chemistry topic that explains how the pH changes during the titration process and illustrates the use of pH indicators.
titration process between hydrochloric acid (HCl) and sodium hydroxide (NaOH) and explain the expected titration curve.
In a titration, a base (NaOH) is slowly added to an acid (HCl) until the equivalence point is reached, where the moles of acid are stoichiometrically equal to the moles of base. The titration curve typically shows the pH of the solution as the volume of the titrant (NaOH) is added.
Initially, the pH is low due to the presence of excess HCl. As NaOH is added, the pH gradually increases, and a buffer region is observed where the pH changes more slowly. The buffer region is followed by a steep rise in pH near the equivalence point, signaling the consumption of the acid. After the equivalence point, the pH stabilizes at a higher value, indicating excess base.
Understanding the curve involves recognizing key points like the initial pH, buffer region, equivalence point, and post-equivalence behavior.
The solution in the flask past the arrow at point B on the curve can be best characterized as a solution of a strong base.
The curve is a titration curve for the titration of HCl by NaOH means that the pH of the solution in the flask is initially acidic (low pH) and then increases as NaOH is added.
Point B is past the equivalence point of the titration. The equivalence point is the point where all the acid has been neutralized by the base. At this point, the pH of the solution is neutral (pH 7).
Past the equivalence point, the pH of the solution increases rapidly with the addition of more base. This is because the excess base starts to react with the water in the solution, producing hydroxide ions (OH-). Hydroxide ions are responsible for the basic properties of a solution, so an increase in their concentration raises the pH.
Strong bases dissociate completely in water, meaning all their ionic bonds break apart and release ions and results in a high concentration of hydroxide ions in the solution, even if a small amount of base is added.

Describe sunspots and how they impact the overall energy of the Sun.
Sunspots are darker, cooler areas on the surface of the sun in a region called the photosphere. The photosphere has a temperature of 5,800 degrees Kelvin. Sunspots have temperatures of about 3,800 degrees K. They look dark only in comparison with the brighter and hotter regions of the photosphere around them. hope this helps
Answer:
A temporary procedure on the photosphere of the Sun, which seems as spots darker in comparison to the enclosing regions is known as sunspots. They are the areas of diminished surface temperature resulting due to the concentrations of the magnetic field flux, which prevent convection. The appearance of sunspots generally appears in pairs of reverse magnetic polarity. The size of sunspots vary and they can be as big as the size of the Earth, they are the dark spots created on the surface of the Sun, and usually enhances the overall energy of the Sun.

Considering only ions with charges of +1, +2, -1 and -2, or neutral atoms, give the symbols for 4 species that are isoelectronic with the iodide ion, I-. .
Some species that are isoelectronic with the iodide ion, I-, include the bromide ion, Br-, krypton, Kr, rubidium ion, Rb+, and tin ion, Sn2+.
Explanation:The iodide ion, I-, has an atomic number of 53 and a charge of -1. To find species that are isoelectronic with the iodide ion, we need to look for ions or neutral atoms that have the same number of electrons as the iodide ion. The number of electrons in the iodide ion is 54 (53 protons + 1 extra electron).
Some species that are isoelectronic with the iodide ion, I-, include:
Bromide ion, Br-Krypton, KrRubidium ion, Rb+Tin ion, Sn2+These species all have 54 electrons, which is the same as the iodide ion.
Final answer:
Some examples of species that are isoelectronic with the iodide ion, I-, include the chloride ion (Cl-), bromide ion (Br-), potassium ion (K+), and calcium ion (Ca2+).
Explanation:
The iodide ion, I-, has a charge of -1. To find species that are isoelectronic with the iodide ion, we need to find other ions or neutral atoms that have the same number of electrons as the iodide ion. Some possible examples are:
Cl- (Chloride ion): has the same electronic configuration as the iodide ion because they both have 54 electrons.Br- (Bromide ion): also has 54 electrons, making it isoelectronic with the iodide ion.K+ (Potassium ion): Although it is a cation, the potassium ion has 18 electrons, which is the same as the iodide ion.Ca2+ (Calcium ion): This cation has 54 electrons, making it isoelectronic with the iodide ion.Suppose you were balancing a chemical equation that contained the substance sodium nitrate, NaNO3, composed of a sodium ion, Na+1, and a nitrate ion, (NO3)-1. Could you change any of these numbers in order to balance the equation?
Explanation:
When a reaction equation contains equal number of atoms on both reactant and product side then this type of chemical equation is known as balanced chemical equation.
For example, multiply this equation by 2 as follows.
[tex]2Na^{+} + 2NO^{-1}_{3} \rightarrow 2NaNO_{3}[/tex]
When sodium ions chemically combine with nitrate ions then it results into the formation of sodium nitrate.
Number of atoms on reactant side are as follows.
[tex]Na^{+}[/tex] = 2
[tex]NO^{-1}_{3}[/tex] = 2
Number of atoms on product side.
Na = 2
[tex]NO_{3}[/tex] = 2
Therefore, as it contains same number of atoms on both reactant and product side.
Also, we can never change the subscripts present in a reaction equation but we can change the number of coefficients on each side in order to balance a chemical equation.

What are intermolecular forces ?Intermolecular forces, such as the electromagnetic forces of attraction or repulsion that act between atoms and other kinds of nearby particles, such as atoms or ions, mediate interactions between molecules.
London's dispersion forces (LDF), dipole-dipole interactions, and hydrogen bonds are the three different intermolecular forces. All substances at least have LDF, but molecules can have any combination of these three types of intermolecular interactions.
Because they affect how a substance behaves physically, intermolecular forces are significant. Since water can form hydrogen bonds with other molecules, many of its life-sustaining qualities, such its high heat capacity, are the result of intermolecular forces.
Thus, option D is correct.

When a substance does not dissolve in another substance, it is said to be... (answer goes here)
Final answer:
When a substance does not dissolve in another substance, it is termed insoluble. Immiscible refers specifically to two liquids that do not mix, and solubility is the extent to which a substance dissolves.
Explanation:
When a substance does not dissolve in another substance, it is said to be insoluble. This term applies widely within the context of solutions in chemistry. For instance, sodium chloride is soluble in water but insoluble in hexane (C6H₁₄). Another important term is immiscible, which is used specifically when two liquids do not dissolve into each other, such as oil and water. This contrast with substances described as miscible, which can blend in all proportions to form a homogeneous solution, like ethanol and water. A partially miscible substance, like n-butanol in water, forms a solution only up to a certain concentration. An unsaturated solution can still dissolve more solute, whereas a saturated solution cannot dissolve any additional solute. Ionic compounds that are termed 'insoluble' still dissolve to some extent, just not in a significant enough amount to affect observations.

give an example of convection you experience in your evrey day life
Answer:
•steaming cup of hot tea - The steam you see when drinking a cup of hot tea indicates that heat is being transferred into the airmark me as brainliest pls
Final answer:
Convection is the transfer of heat through the movement of fluids, such as the warm air circulation caused by a heater or the water cycling in a boiling pot.
Explanation:
Convection is a fundamental concept in Physics related to the movement of fluids (liquids or gases) as a result of heat transfer. When a fluid is heated, it becomes less dense and rises, whereas cooler fluid descends to take its place, creating a convection current. An everyday example of convection that we experience would be the warm air circulating in a room when a heater is on. As the heater warms the air, this air rises because it is less dense. Cooler air moves in to replace it, gets warmed up, and the cycle continues, resulting in a circulation of air and an overall warming of the room.
Another common example of convection is seen when you boil water in a pot. The water at the bottom gets heated first and rises to the surface, while the cooler water above descends to the bottom of the pot, creating a convection current that helps to evenly heat the water.

how is the modern atomic model similar to bohr's model?
Bohr thought that electrons orbited the nucleus in circular paths; whereas in the modern view atomic electron structure is more like 3D standing waves. Bohr built upon Rutherford's model of the atom. ... He believed that electrons moved around the nucleus in circular orbits with quantised potential and kinetic energies.
Modern atomic model is similar to Bohr's atomic model by the fact that an atom has a nucleus around which electrons revolve in circular orbits.
What is Bohr's atomic model?Atomic model presented by Bohr is a system comprising of small dense nucleus surrounded by electrons which is similar to the solar system. The only difference being electrostatic forces in place of gravity.
It is successful in explaining the Rydberg's formula for emission of spectral lines of hydrogen. According to this model, electron is able to revolve in stable orbits around the nucleus without any energy being radiated.
Stationary orbits are obtained at distances for which revolving electrons have an angular momentum which is an integer multiple of Planck's constant. Electrons can only gain or loose energy by jumping from one orbit to another.
