Abstract and Figures Chemical bonding is one of the key and basic concepts in chemistry. Whenever two atoms or ions are strongly attached to each other, we say there is a chemical bond between them. Single bonds have a bond order of one, and multiple bonds with bond orders of two (a double bond) and three (a triple bond) are quite common. The likelihood that the 2 elements will form a chemical bond is determined by the interactions between the VE and the nuclei of elements. By sharing the electron pairs, both atoms also gain a filled outer shell, or an octet.
