If two atoms share one pair of electrons, the formed covalent bond is called single covalent bond. For example, HCl. In HCl, H has 1 electron in its valence shell, while Cl has 7 electrons in its valence shell. H require 1 more electron to complete its doublet, while Cl require only one electron to complete its octate. Therefore, both atoms share a pair of electrons (one electron provided from each atom). This type of covalent bond is shown by ____.
