Is the stability of the noble gas elements other than helium is a result of their having eight valence electrons?
Yes, the stability of noble gas elements other than helium is due to their having eight valence electrons. This electron configuration, known as an octet, gives them a full outer energy level, making them highly stable and less likely to form chemical bonds with other elements.

How is valence and reactivity related?
Valence electrons are the electrons on the outer shell of an atom. Valence electrons help to determine the reactivity of a substance because atoms do their best to "fill" their outer shell with 8 electrons, thus achieving a more stable energetic state. Different atoms have different numbers of valence electrons, which affects their reactivity. For instance, noble gases are inert because they possess a full set of valence electrons and don't need to "borrow" or "give away" electrons to have a full outer shell. Halogens, on the other hand, are 1 electron away from filling their outer shell, and are very reactive as a result (they attempt to "borrow" an electron with other atoms by forming a chemical bond).
How does reactivity change down the group of atoms?
Reactivity generally increases down a group of atoms. This is because as you move down the group, the atomic radius increases and the valence electrons become further from the nucleus. As a result, the valence electrons are less strongly attracted to the nucleus, making them more easily available for bond formation and chemical reactions.
What would barium do to obtain a noble gas structure?
Barium, a group 2 metal, would lose two electrons to achieve a stable noble gas structure like xenon. This would result in a full valence shell and stability, similar to a noble gas atom.

What is argon valence number and electrons and oxidation number?
Argon's valence number is 8, it has 18 electrons, and its oxidation number is 0 because it doesn't react.
Which part of an atom plays a major role in chemical reactions?
Chemical reactions are a result of valence electron transfer and/or sharing. Valence electrons are located in the outer-most orbitals of the reactant elements. In a sense, though, you could say protons are also involved in chemical reactions. Although an element will never donate, accept, or share protons in a CHEMICAL reaction, they are part of the determination in an elements reactivity. Reactions that do involve protons are termed "nuclear reactions," and are not chemical reactions. In fact, a lot of the methods used to determine chemical reactions -- such as enthalpy -- cannot even be applied to nuclear reactions. Neutrons, like protons are involved in nuclear reactions, but never in chemical reactions. Hope this helps!

What happens to electrons when chemicals bond?
An electron is either shared or transferred between atoms when chemicals bond. The goal of covalent bonds is to achieve stability by sharing electrons among the atoms. In ionic bonds, electrons are transferred from one atom to another, forming positively and negatively charged ions.
How is the number of valence electrons of a nonmetal related to the charge on the ion the nonmetal?
Nonmetals will undergo chemical reactions that result in a stable electron configuration of 8 electrons in the outer shell. The number of valence electrons tells you have many they have in their outer shell prior to any chemical reaction, and therefore, how many more electrons they need to get a complete set of 8. So for example, oxygen has 6 valence electrons and therefore needs 2 more to have 8, so it will form an ion with a charge of minus two, which is the charge that is carried by the additional two electrons that oxygen will acquire. Chlorine has 7 valence electrons, therefore it needs just one more electron to complete its outer shell, and as an ion will have a charge of minus one. Nitrogen has 5 valence electrons, so it needs 3 more, and will form an ion with a charge of minus three.
Is neon very reactive or is it not very reactive and why?
Neon is not reactive at all because it has a full p sublevel of electrons (8 valence electrons total). This is a very stable configuration, and as a result, neon is neither a reactant nor a product in normal chemical reactions.
How can an atom that has five valence electron achieve a full set of valence electron?
An atom with five valence electrons can achieve a full set of eight valence electrons by either gaining three electrons (to reach a stable octet) or losing three electrons to have a stable arrangement. This would result in the atom forming an ionic bond, such as in the case of boron transferring three electrons to become the boride ion.
