MCAT Study Setcovalent bond formed via the sharing of electrons between two elements of similar EN bond order refers to whether a covalent bond is a single, double, or triple bond. As bond order increases, bond strength increases, bond energy increases, bond length decreases ionic bonds formed via the transfer of one or more electrons from an element with a relatively low IE to an element with a relatively high electron affinity - cation: postiive - anion: negative elect...
