What is the chemical formula for Magnesium? | Yahoo Answers
Mar 16, 2013· Magnesium hydroxide is an ionic compound which signifys that it is a metal bonded to either another metal or nonmetal. Since the Mg ion has a 2+ charge & the OH ion has a 1- charge. Then when they are coined together they form a neutral charge. The next step is to out the charge of Mg & OH to their correct sides.

Calcium is a silvery white metal. The surface of calcium metal is covered with a thin layer of oxide that helps protect the metal from attack by air, but to a lesser extent than the corresponding layer in magnesium. Once ignited, calcium metal burns in air to give a mixture of white calcium oxide, CaO, and calcium nitride, Ca 3 N 2. Calcium
