For an ionic bonding to occur there must be an electron donor (often a metal) and an electron acceptor (often a nonmetal). The transfer of electrons is referred to as electrovalence. The atom that loses one or more electrons will turn into a ... WebbAs you have learned, ions are atoms or molecules bearing an electrical charge. A cation (a positive ion) forms when a neutral atom loses one or more electrons from its valence shell, and an anion (a negative ion) forms when a neutral atom gains one or more electrons in its valence shell. Compounds composed of ions are called ionic compounds (or ... flexsteel industries inc starkville ms
