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.
group 18, noble gases
Noble gases does not easily combine with other elementsbecause they are stable and have complete outermost shell.
the noble gases have octet configuration ie they have 8 electrons in their outermost shell ,so they are stable
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.
the noble gases have their valence shell complete
group 18, noble gases
it is Helium.

the noble gases have octet configuration ie they have 8 electrons in their outermost shell ,so they are stable
Inert gases
These are the noble gases which have a complete valence shell.
The noble gases
The Noble Gases, group 18 (or VIIIa) of the periodic table, have complete outermost shells. They are helium, neon, argon, krypton, xenon, and radon.
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.
No. Because they already have 8 electrons in their outermost shell and they are stable
the noble gases have their valence shell complete
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
