It has two carbon (C) atoms, four hydrogen (H) atoms and two oxygen (O) atoms. Write it as CH3COOH and it is obvious this a carboxylic acid- ethanoic or acetic acid. Unlike covalent bonds, in which electron pairs are shared between atoms, an ionic bond is formed when two oppositely charged ions attract one another. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding. The presence of an acetyl group in a single molecule of acetic acid is central to its role in the metabolism of living organisms. Acetic acid can be produced a few ways, natural and synthetic. Atoms have the same number of protons and neutrons and atoms make up a molecule. As such, we refer to one piece of NaCl not as a molecule but as a formula unit.
