The Reactivity Series of Metals Towards Oxygen The reactivity of metals differs from one metal to another. In fact, the form in which a metal occurs in nature depends on its reactivity. Gold has very low reactivity and therefore can be found in its metallic state in
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 .
Calcium - Wikipedia
The chemistry of calcium is that of a typical heavy alkaline earth metal. For example, calcium spontaneously reacts with water more quickly than magnesium and less quickly than strontium to produce calcium hydroxide and hydrogen gas. It also reacts with the oxygen and nitrogen in the air to form a mixture of calcium oxide and calcium nitride.
