There are six noble gases: helium, neon, argon, krypton, xenon and radon. All have completely filled outermost shell. Helium has 2 valence electrons while the other elements have 8 valence electrons.

What are valence electrons and how do they relate to the noble gases?

Valence electrons are electrons in the outermost shell (or outermost energy level or outermost orbital) in an atom. Noble gases have 8 valence electrons. But helium (a noble gas) has only 2 valence electrons.

Is O a molecule?

O is the symbol for Oxygen, which is not a noble gas.No, Oxygen (O) is in group 6 and the noble gases (or inert gases) are in group 8.oxygen is not a noble gas because in order to become a noble gas it is necessary to have a completely filled outermost shell. as oxygen has only 6 electrons in its outermost shell it is not a noble gas because noble gases have 8 electrons which completely fill the outermost shell
