Answer: Both Mg2+ and Ca2+ are important biological ions.
Chapter 8, Problem 134P(choose chapter or problem)
Both \(\mathrm{Mg}^{2+}\) and \(\mathrm{Ca}^{2+}\) are important biological ions. One of their functions is to bind to the phosphate groups of ATP molecules or amino acids of proteins. For Group 2A metals in general, the tendency for binding to the anions increases in the order \(\mathrm{Ba}^{2+}<\mathrm{Sr}^{2+}<\mathrm{Ca}^{2+}<\mathrm{Mg}^{2+}\). Explain the trend.
