Carbon atoms may thus form bonds to as many as four other atoms. For example, in methane (CH 4 ), carbon forms covalent bonds with four hydrogen atoms. Each bond corresponds to a pair of shared electrons (one from carbon and one from hydrogen), giving carbon the eight electrons it needs for a full outer shell.
