Basic Atomic Structure and Chemical Bonding Goals: Understand
... While larger elements will have greater numbers of electrons, there are only a few that we actually care about. The electrons on the very outside of the atom are the ones that we will focus on. They are the ones involved with chemical bonding, and therefore the most important. The number of valence ...
