The charge of an ion is determined by the amount of electrons compared to the number of protons, so a charge of +2 indicates that the ion has two more protons than electrons. While it is possible to force oxygen into an oxidation state of 2, 1, or -1. You can determine the ground-state electron configuration of Strontium (Sr) by referring to the periodic table and locating the position of Sr in the periodic table. The increased polarity enhances ligand lability and the nucleophilicity of simple organic groups, causing the organometallic derivatives to be more reactive and unstable. Strontiumranelat ist ein Arzneistoff zur Behandlung der Osteoporose. The larger size : charge ratios and ionic radii of calcium, strontium and barium ions, relative to those of magnesium, impart a greater ionicity on compounds of the heavier metals and promote higher coordination numbers.
