The bond is typically between a metal and a non-metal. A brief treatment of ionic bonds follows. The oppositely charged ions are strongly attracted to each other, forming ionic bonds. An electrically neutral entity consisting of more than one atom (n>1). • Ionic compounds occur when a metal cation(+) and a non-metal anion(-) attract and bind. Making statements based on opinion; back them up with references or personal experience. Non-metals gain electrons because they have 5,6 or 7 outer shell electrons The covalent bond is a bond formed when two atoms share one or more electron pairs. An ionic bond is actually the extreme case of a polar covalent bond, the latter resulting from unequal sharing of electrons rather than complete electron transfer. Your answers are right.
