It increases
The attractive force between the nucleus and the electrons INCREASES if the proton number increases while the number of energy levels remains constant.
Explanation:
Remember that protons carry a positive charge while electrons carry a negative charges. Unlike charges attract while like charges repel. An increase in the number of protons increases the positive charge of the atomic nucleus. This means that the force of attraction on the electron cloud of the atom increases.
This is why the atomic radius of atoms decreases across a period (from left to right) as the mass number of the atoms increase (while the number of electron orbitals remains the same across the period).

Answer:
c, atoms
Explanation:
Molecules are made up of atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among atoms. The atoms of certain elements readily bond with other atoms to form molecules. Examples of such elements are oxygen and chlorine.

I’d say A yeah I’m pretty sure
Answer:
When an electron absorbs energy, it will move up from a lower energy level to a higher energy level, called the "excited state" of the negatively-charged subatomic particle.
Answer:
The answer to your question is K = 1.48
Explanation:
Balanced chemical reaction
Br₂ + I₂ ⇒ 2IBr
Process
1.- Calculate the concentration of each of the reactants
[Br₂] = 0.6 mol / 1 L
= 0.6 M
[I₂] = 1.6 mol / 1 L
= 1.6 M
[IBr] = 1.19 M
2.- Write the equation of the Equilibrium constant
K = [IBr]² / [Br₂][I₂]
-Substitution
K = [1.19]² / [0.6][1.6]
- Simplification
K = 1.4161 / 0.96
- Result
K = 1.48
