Yes. Only the valence shell will interact with other atoms. This is how different elements are different from eachother. The electrons under the valence shell are never touched. Yes.

Atoms with outer electron shells that contain 8 electrons tend to be stable and chemically in reactive, or inert.
Because the shell can only hold eight electrons. check
Chemical bonding is driven by several different mechanisms by which atoms obtain more stable arrangements of their outer electron shells. The basic rule is, complete outer shells are more stable. The smallest atoms can have complete outer shells with just two electrons (or even with zero electrons, in the case of hydrogen) but most atoms require eight electrons in the outer shell (which is known as the octet rule). Atoms can either share electrons with other atoms (forming covalent bonds or in the case of metals, metallic bonds) or exchange electrons with other atoms (forming ionic bonds). In minerals, most of the bonds are ionic. Atoms with too many electrons give excess electrons to atoms with too few electrons and they both become more stable, and also acquire electrical charges. They then attract each other, due to their electrical charges (opposite charges attract, as stated by Coulomb's Law) and that is how they connect to form minerals or other compounds.
8 electrons and yes, the Octet rule states this
The atoms of the molecule effectively achieve a noble gas configuration by sharing valence electrons.
they add or loose electrons from the outer most shells
The answer varies between different atoms -Kill_Me0215
They share electrons when they try and corm covalent or ionic bonds. This is because the atoms want to gain a full outer shell. So when they share electrons they can have full shells.
The table was organized so that elements of similar properties are in the same group. What (partly) determines reactivity is the number of electrons an atom has in it's ground state. . Within the atom electrons are organized in shells. Atoms are stable when they have 8 electrons in their outer shell (for hydrogen and helium it is 2 electrons.) . Elements of: Group 18 have 8 electrons in their outer shells Group 17 have 7 electrons in their outer shells Group 16 have 6 electrons in their outer shells Group 15 have 5 electrons in their outer shells Group 14 have 4 electrons in their outer shells Group 13 have 3 electrons in their outer shells Groups 3-12 have varied number of electrons in their outer shells Group 2 have 2 electrons in their outer shells Group 1 have 1 electron in their outer shells
A covalent bond is formed when sharing electrons.
The happy atoms are the noble gases. They don't react because their valence electron shells are full. The goal of every element is to have the most outer shell of electrons full. The first shell holds 2 electrons, and every shell after that holds 8 electrons. So helium and hydrogen both want to have 2 electrons in their outer shells. Elements like neon and argon have 8 electrons in their outer shells. Atoms like chlorine and fluorine have 7 electrons in their outer shells. This means that aren't "happy" because they want to have 8. This is why they ionically bond with atoms like sodium that have 1 electron in their outer shells. Sodium gives that electron to chlorine and now both have 8 electrons in their outer shells.
Atoms with outer electron shells that contain 8 electrons tend to be stable and chemically in reactive, or inert.
Neon, plus the other noble gasses, but these other noble gases also have additional electrons in outer shells.

These atoms are very stable and unreactive.
