Nitrogen has five valence electrons.
nitrogen has 5 valence electrons. carbon has 4 valence electrons.
if you are talking about valence electrons: 3. if you are talking about regular electrons, it differs. there are different atoms in that category. scandium 21 yttrium 39 lutetium 71 lawrencium 103 i hope this helps
