6. Aluminum metal is oxidized by oxygen (from the air) to form aluminum oxide. 4 Al (s) + 3O2 → 2 Al2O3 7. Sodium oxide reacts with carbon dioxide to form sodium carbonate. Na2O + CO2 → Na2 CO3 8. Calcium metal reacts with water to form calcium
Group 2 The Alkaline Earth Metals
It is somewhat difficult to ignite, in character rather like magnesium, but when lit, the metal burns in air with a brilliant high-intensity red light. 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.

Is calcium a metal
Calcium is a reactive alkaline earth metal that develops a dark oxide-nitride layer when exposed to air Calcium is a metal but calcium carbonate is not. calcium is a metalloid as it stands between metal and non metal as it doesn''t have all the porperties of metal
Metals - Fun Science
For example, Na is a metal because it can form positive ion (Na+) ion by losing an electron from its outermost shell. In the same way Iron, aluminium, copper, gold, silver, magnesium, potassium and calcium are also metals because all of these elements can form positive ions by losing electrons.
