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 Webb2 apr. 2024 · Atoms with high reactivity have outer shells that are imbalanced because of a low number of electrons (one or two) or a higher but not full number (six or seven). The most highly reactive elements are halogens, which are looking to gain one more electron, and alkali metals, which are looking to lose the single electron in their outer shells.

Webb6 mars 2024 · Valence electrons are the electrons contained in the outermost shell. If you look at the periodic table and at the period numbers, that is the number of valence electrons. If the number is larger than 10, subtract 10 so you get two valence electrons. Example: Oxygen is in the 16th period.
