Whats a valence electron? ?

Question

my book doesnt explain anything!

Answer 1

It's been a long time, but as I remember it, they're the ones that are on the outer edges of the atom, and which ultimately get shared when bonds are formed.

Answer 2

valence electrons means the outer most electrons present in an atom.

these participate in the reaction.this is either giving or taking (ionic bonding) or sharing (covalent bonding) after this ,the atoms become ions i.e they become positively or negitively charged.hope this helps!!!

A valence electron is an electron in the outer shell of an atom. These electrons are the ones that participate in reactions.

Answer 4
