Because they have filled outer shells. So there is no advantage to donating or accepting electrons, no to sharing electrons #$#

Because they are stable. They have an octet around them - meaning 8 valence electrons causing them to be stable. Most elements are reactive because they dont have a full outer shell of valence electrons around them (8 electrons). Take carbon for example - it is in column 4 - which also means it has 4 valence electrons (noble gases are in column 8.... ) so carbon needs to share 4 more electrons to be stable and neutral. so a molecule of CH4 is stable because the carbon has its own 4 valence electrons and then is sharing the 1 electron from each of the 4 Hydrogens... therefore it has an octet of 8 electrons surrounding it. It is the same thing with the noble gases except that they ALREADY have 8 valence electrons and dont have to share.

Actually, some noble gases react under certain circumstances. Xe reacts with F2 to produce XeF6, and XeF6 reacts with water to give XeO3.

All of the outer shell electrons are paired with others of opposite spin.

because of the octet rule, and because noble gases have 8 electrons in their outer most shell they are "happy" because they fulfill the octet rule.

their energy levels are filled with an equal balance of protons in the nucleus.
