If you mean valence electrons, then valence electrons are the number of electrons an atom has in its outer level. If you look on a Periodic Table, the fastest way to do this is to look at what column they are in. If it is in column one, it has one valence electron. Just don't use this rule for metals (rows 3-12) because the rule does not apply to metals. Hope this helped!
