how many valence electrons does an atom of the element neon (ne) have?
How many valence electrons does neon have? Best Answer: Valence electrons are found by finding what column (out of the 8 highest) the element is in on a periodic table. Neon lies in the 8th column, so it has 8 valence electrons. Valence refers to the Valence Shell - that is the outermost layer of electrons - and is bound to the Octet Rule, meaning that molecules try their hardest to have 8 electrons in their outermost shell (making up the noble gasses, except Helium). Neon has 2 electrons in its inner shell and 8 in its Valence Shell. Cheers!
