Compare covalent bond. The second was even better – deep and subtle. The atom that loses the electrons becomes a positively charged ion (cation), while the one that gains them becomes a negatively charged ion (anion). Ionic Bond: Covalent Bond: The ionic bond is the attraction between positive and negative ions in a crystal and compounds held together by ionic bonds are called ionic compounds.
