Comments “Insight into the interesting biological roles and properties of Mg2+ may be gleaned from consideration of the basic chemical properties of Mg2+, properties that make it unique amongst biological cations. The size of a Mg2+ cation and some derivative properties are compared to those of K+, Na+ and Ca2+ in Table 1. The ionic radius of Mg2+ is substantially smaller and it’s hydrated radius substantially larger than that of the other three cations.”
