#### calcium | Definition, Properties, & Compounds | Britannica

The metal reacts slowly with oxygen, water vapour, and nitrogen of the air to form a yellow coating of the oxide, hydroxide, and nitride. It burns in air or pure oxygen to form the oxide and reacts rapidly with warm water (and more slowly with cold water) to produce hydrogen gas and calcium hydroxide.

#### Calcium (Ca) - Chemical properties, Health and …

Calcium The chemical element Calcium (Ca), atomic nuer 20, is the fifth element and the third most abundant metal in the earth’s crust. The metal is trimorphic, harder than sodium, but softer than aluminium.A well as beryllium and aluminium, and unlike the alkaline metals, it doesn’t cause skin-burns.

#### metal that react more than calcium introductions

Which is more reactive calcium or zinc strontium is more reactive than calcium because it is more electropositive. valance electrons of strontium are farther away hence it will react with the reactive metal (calcium). Zn(NO 3 ) 2
