Can be obtained from: Chalk, limestone and marble. Is found in 3.5% of Earth’s crust. Bones, teeth and shells are formed by calcium.
found as calcium sulfate in alabaster and gypsum, calcium fluoride in fluorite, or as calcium phosphate in rock phosphate
In nature, calcium is found in rocks, chalk and seashells. It is found in the bones, muscles and nerves of many animals and plants. Calcium is abundant.
Its has a slightly grayish appearance when it is first cut. Then the air tarnishes it to show a duller finish. Reacts with water.
Its compounds are used to make plaster, and metallurgic and electronic materials. ube.com/watch ?v=HSV3jOccyY s
