List two chemical properties and two physical properties of the element magnesium. (You may use your textbook.)

Sagot :

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 it's density 1740 kg/m3 (0.063 lb/in3 or 108.6 lb/ft3).Th density of magnesium is 1.738 g/mL, which means the metal will sink in water, but it is still relatively light weight. Chemical Properties:Magnesium is a silvery white metal. The surface of magnesium metal is covered with a thin layer of oxide that helps protect the metal from attack by air.
