Calcium oxide (CaO) is an ionic compound composed of calcium and oxygen ions, and it is named calcium oxide following the nomenclature rules for ionic compounds.
Calcium oxide (CaO) is an ionic compound formed by the combination of a metal (calcium) and a non-metal (oxygen). In ionic compounds, the metal donates electrons to the non-metal, resulting in the formation of charged ions. In the case of CaO, calcium (Ca) loses two electrons to form a Ca²⁺ ion, while oxygen (O) gains two electrons to form an O²⁻ ion. The combination of these ions results in the formula CaO.
From the perspective of nomenclature, CaO is named calcium oxide. The name reflects the composition of the compound and adheres to the rules of naming ionic compounds, where the metal's name is followed by the non-metal's name with the suffix "-ide."
The probable question may be:
What’s the name for the following ionic compound - CaO.
