How come it is that outer shell electrons participate in bonding and not the electrons that in other shells?

Inner shells of electrons are always full and cannot accept any additional electrons. Also, they can not generally lose electrons because the energy require to remove an electron from an inner shell is generally too high to be achieved in a chemical reaction.

What are valence electrons and shells?
Valence electrons are the ones which participate in chemical reactions in some way, either by moving from one atom to another, or by being shared with another atom. They are found in the outer shell of an atom (there are usually inner shells with other electrons that are not valence electrons, although in the lightest elements, there are no inner shells and all electrons are valence electrons).
How do valence electrons influence molecular bonding?
Since the valence electrons are the outermost electrons of atoms, they have the highest opportunity to overlap with other orbitals in the valence shells of other atoms. Therefore, they influence the most in forming bonds.
Why are noble gases are non reactive?
They have filled valence shells. Atoms undergo chemical bonding in order to have filled valence shells by sharing electrons or transferring electrons. Because the noble gases already have filled valence shells, they have no need to react with other elements.
What group on the periodic table has the most stable amount of valence electrons?
That would be the Nobel gasses, 8A, because they have an octet of 8 electrons fully filling their valance shells so that they naturally do not react with other elements is either ionic or covalent bonding.
How are the Noble gases different from the other families on the periodic table?
Noble gases' outermost electron shells are completely full. With any element, the first shell needs to contain two electrons - only two elements, hydrogen and helium, have only one shell - and the outer shell of an atom with two or more shells must contain eight electrons. It can get there by having enough electrons on its own, or by bonding with other atoms and sharing the electrons. (In some cases atoms take this to the extreme: alkali metals, which have one electron in their outer shells, form salts by sharing seven electrons from a halogen atom.) Because noble gases' outermost shells are full, they don't have to - and in most cases will refuse to - bond with other atoms.Having said that, argon will form a very few compounds...and all of them contain fluorine, which is so reactive it can strip electrons from noble gas atoms.

How the number of electrons in an atoms electron shells is the basis for chemical bonding?
Atoms bond because they "share" their electrons. Every atom wants to have 2 atoms in their first shell, and then 8 in all the other shells. Lets say we have an atom with 3 electrons, and one with 9 electrons, they will esaly bond
Where are valence electrons located and why are they so important?
They are on the outermost level of the electron shells. On the periodic table the valience electrons increase as they go over in groups. Valence electrons are located at the highest energy level present in an atom and they are almost responsible for its chemical properties. They are the electrons that participate in chemical reactions.

What happens when ionic bonding occurs between two atoms?
I think you mean, 'What happens when ionic bonding occurs between two elements' In ionic bonding two or more elements share electrons from their outter shells, usually resulting in full, stable outter shells like the noble gases.
What is the bonding process for nonmetals bonding with metals?
the bonding process for nonmetals bonding with metals is that they can take electrons and give them to each other.
How many bonding electrons does oxygen have?
The valence electrons are the electrons in the partially filled outermost shell (or shells).Simplified; Oxygen has the shells filled in the following way.1s22s22p4The 2s and 2p subshells make up the outer most shell for oxygen. In the 2p subshell, It is stable with 6 electrons but with oxygen only has 4. The subshell has 3 different orbitals which can contain 2 electrons in each. This means that 1 of the orbitals is completely full while the other two only have one electron. From this we can say that there are 2 bonding valence shell electrons. Because there is a possibility of having a total of 8 electrons in the 2nd shell, this means that there must be 4 electrons which are non bonding in oxygen's valence shell.
What are electrons in the outer shell called?
valence electrons, they are the ones responsible for bonding with other atoms.

That would be the Nobel gasses, 8A, because they have an octet of 8 electrons fully filling their valance shells so that they naturally do not react with other elements is either ionic or covalent bonding.
