WebLewis' Theory of Chemical Bonding Covalent Bonds Lewis' second great idea was this: two atoms attract each other (create a covalent bond) by sharing a pair of electrons. Lewis claimed that the shared electrons became part of each atom's electron configuration, so sharing effectively boosts each atom's electron count.
