Magnesium - Mg. Chemical properties of magnesium - Health effects of magnesium - Environmental effects of magnesium. Magnesium. Chemical element, metallic, symbol Mg, situated in group IIa in the periodic table, atomic number: 12, atomic weight: 24,312. Magnesium is silvery white and very light. Its relative density is 1,74 and itâs density 1740 kg/m3 (0.063 lb/in3 or 108.6 lb/ft3).
If it's neutral, then it'll have the properties of a metal and its number of electrons will equal to its protons or its atomic number. So the answer would be 12. But if you're talking about magnesium in the sea or magnesium in rocks and minerals, that's an ion in the form of Mg2+.
