What is the reaction between aluminum and oxygen? - …

Oxygen reacts with aluminum by creating a passivating layer of Al2O3 on the aluminum surface, stopping further reaction because fresh oxygen cannot penetrate that layer to reach the unreacted metal. At higher temperatures, aluminum will melt and burn in an oxygen atmosphere, again to form Al2O3.

The surface of barium 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, barium metal burns in air to give a mixture of white barium oxide, BaO, and barium nitride, Ba 3 N 2 .

Calcium

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 .
