What happens when calcium oxide is heated? | Yahoo Answers

Jun 12, 2011· Best Answer: Metal oxides are, for the most part, very thermally stable, and do not easily decompose with added heat. Calcium oxide is one of those substances. Even the metal oxides will eventually decompose to the elements when heated to a high enough temperature. CaO glows when heated to about 2400 C, but

Oxide | chemical compound | Britannica

Oxides of the transition metals with oxidation nuers of +1, +2, and +3 are ionic compounds consisting of metal ions and oxide ions. Those transition metal oxides with oxidation nuers +4, +5, +6, and +7 behave as covalent compounds containing covalent metal-oxygen bonds. As a general rule, the ionic transition metal oxides are basic.
