WebThe requirements for the formation of an ionic bond are an atom that will lose one or more electrons and an atom that will gain one or more electrons. Neither of these processes can require a large amount of energy. For this reason, ions with charges of + 1, −1, +2, and −2 are much more common than those with charges of + 3 or -3 or more.
