a chemical bond formed between ions with opposite charges and are held together by an electrical charge; the electrons are usually exchanges
ionic bond
a type of chemical bond formed when atoms share electrons
covalent bond
a charged atom that has lost or gained electrons giving them a positive or negative charge
ion
