In one of the types of bonds, PAIRS of electrons are shared. There are other electrons that do not participate in the sharing. What are these electrons called?
lone pairs, unshared pair, nonbonding pairs
300
What is the difference between ionic and covalent bonding?
ionic- one gives, the other takes electrons; covalent- they share pairs of electrons
400

Which of the following would NOT bond covalently? CO2, LiCl, CCl4, H2O
LiCl is ionic

Why are there no charges on the atoms after they've bonded covalently?
Because they are not "gaining" or "losing" electrons. They are sharing.
