The oxidation state is the indicator of the degree of oxidation of an atom in a chemical compound. The formal oxidation state is the hypothetical charge that an atom would have if all bonds to atoms of different elements were 100% ionic. Oxidation states are typically represented by integers, which can be positive, negative, or zero. Relative Pauling electronegativity values can be inferred from an element’s common and uncommon oxidation states. A new method of displaying oxidation states is reported here. Hexagonal cells can be used to optimum advantage to indicate common and uncommon oxidation states. A spiral arrangement formed of such cells shows the strong correlation between electronic configuration, electronegativity, and oxidation states. Various arrangements of the periodic system, selected examples of which are reported here, can and have been used to emphasize various atomic properties. A review of the imagery indicates that the spiral hex arrangement is well suited to a simple design convention that efficiently and effectively conveys the interactions among the elements. © 2014 Jeff Moran.
