Covalent bonds: Covalent compounds are formed when nonmetals share valence electrons forming a covalent bond. Ionic bonds: Ionic compounds are formed when metal atoms transfer electrons to nonmetal atoms resulting in the formation of ionic bonds. Covalent bond: Share electrons with nonmetal to form a covalent bond Ionic bond: transfer electrons from metal to nonmetal to form covalent bond - electron donor and an electron acceptor (cation and anion) Covalent: water, H2O 2 H atoms + 1 O ato...
