The Octet Rule - correct answer Main group elements (groups 1, 2, and 13-17) tend to form bonds so that they have an "octet" of electrons (8 electrons) Noble gases - correct answer • Noble gases usually exist as single atoms and do not tend to form compounds; this is because they have completely filled orbitals. • Noble gases have filled s and p orbitals in the outermost shell Valence electrons - correct ans...
