The valence electrons of Neon is 8. Neon has the atomicnumber 10. It is a stable noble gas.
Valence electrons are the total number of electrons present in the outermost shell of an atom. The valence electron for neutral atom is always definite. Neon has eight valence electrons, a full octet that makes neon quite stable Noble gas. This can be confirmed via it's electronic configuration by looking at the highest energy level which is 2 in this case
The electronic configuration of Neon is,
1s2 2s2 2p6 or [He] 2s2 2p6
Here, the 2s orbital holds two valence electrons while the 2p orbital holds the other six valence electrons. so there are 8 valence electrons that is a full octet.
