15.09.2020· Answers : (1) abhay gupta. askIITians Faculty. 178 Points. Explanation: After calcium reacts with water, hydrogen gas is released in the reaction. This bubbles of hydrogen gas stick to the surface of the metal. The buoyancy of the gas bubbles lifts the calcium up. Therefore, calcium floats on water.

WebElements Periodic Table » Calcium » …

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.
