The debate related to origin of the term "hypervalent" that was first introduced by Jeremy Musher in 1969 to describe compounds and complex ions of the heavier main-block elements in which the use of traditional Lewis 2c-2e covalent bonds requires the additional assumption of "octer expansion" for the central atom is presented. The traditional Lewis 2c-2e model of covalent bonding is still important in introductory chemistry textbooks, because they are a necessary component of the highly successful VSEPR model for the prediction of molecular geometries.
