The outer electrons of an atom

WebbAll that this means is that silicon has a core structure that is the same as neon, but then has four more electrons (3s2 3p2). It's just a short cut and it is commonly used. Furthermore, it is helpful because the outer electrons (3s2 3p2) are the valence electrons and these are the ones that are of most importance. 2 comments ( 10 votes) Upvote Webb5.2 Electron Arrangement In Atoms. 19 terms.
