Ionic bond: bond in which one or more electrons from one atom are removed and attached to another atom, resulting in positive and negative ions which attract each other.Other types of bonds include metallic bonds and hydrogen bonding.hemical Bonding. Chemical compounds are formed by the joining of two or more atoms. A stable compound occurs when the total energy of the combination has lower energy than the separated atoms.
Ionic and covalent bonds are the two major types of chemical bonds, which connect atoms in a chemical compound. Ionic Bond. Atoms can gain or lose electrons and form negative or positive charged particles. These particles are called ions.
