2. Alkaline Earth Metals Date of Discovery: 1808 Discoverer: Sir Humphry Davy The picture above shows the colour arising from adding barium chlorate (BaClO3) to a burning mixture. Wiley Valdez ABC# 1-19 2 Barium

3. Alkaline Earth Metals The element was called barium because it was found in barite (barium sulfate) a mineral given its name because of its high density. Wiley Valdez ABC# 1-19 3 Barium

6. 5 th most abundant element in the earth’s crust Calcium is the most abundant of the metallic elements in the human body. The average adult body contains about 1 kg or 2 lb. of calcium, 99% of which is in the bones and teeth. Calcium is not naturally found in its elemental state but calcium compounds are common Pure calcium metal reacts quite vigorously with water generating hydrogen gas Calcium salts are used to produce a deep orange color in fireworks
