Answer to Question #131790 in General Chemistry for adiele

Question

Compare and contrast ionic and covalent bonds in terms of definition, strength, chemical arrangement and examples of each in living systems

Answer 1

Covalent bond is a bond between nonmetals sharing their electrons, which become common for two different atoms. The example of a covalent bond is a double covalent bond in a molecule of oxygen.

Ionic bond is a bond between metal and nonmetal with a transfer of an electron from a metal to a nonmetal. Electrostatic force arises between charged atoms called ions, which are surrounded by oppositely charged particles. Ionic bond is the strongest. The example of an ionic bond is a bond in sodium chloride.
