WebElements Periodic Table » Calcium » reactions of …

Calcium is a silvery white metal. The surface of calcium metal is covered with a thin layer of oxide that helps protect the metal from attack by air, but to a lesser extent than the corresponding layer in magnesium. Once ignited, calcium metal burns in air to give a mixture of white calcium oxide, CaO, and calcium nitride, Ca 3 N 2.

Explain why calcium metal after reacting with water starts …

Calcium starts floating because the bubbles of hydrogen gas formed stick to the surface of metal. Ca(s) +2H 2 O(l) →Ca(OH) 2 +H 2 (g) Magnesium reacts with hot water and starts floating due to the bubbles of hydrogen gas sticking to its surface.
