Barium - Simple English Wikipedia, the free encyclopedia
Barium is too reactive as a metal, so it is not found in the earth as a metal. It is found in chemical compounds. Barium only occurs in one oxidation state: +2.Most barium compounds are colorless. The ones that dissolve in water or stomach acid are very toxic.

Most calcium and magnesium supplements contain a ratio of two parts calcium to one part magnesium. The logic behind this ratio is based on the relative amounts of these nutrients used in the body. But in order to determine how much we might need to take as a supplement, we should consider how much of these nutrients we are getting in our food and how they are stored and recycled in the body.

Group 2 The Alkaline Earth Metals
Calcium metal reacts with water, evolving hydrogen gas at a rate rapid enough to be noticeable (unlike its sister magnesium) but not fast enough at room temperature to generate much heat. Part of the slowness of the calcium-water reaction results from the metal being partly protected by insoluble white calcium hydroxide.
