Question

what is the name for the ionic compound caf₂?
calcium fluorine
cesium fluorine
calcium fluoride
cesium fluoride

Explanation:

Ionic compounds are named by stating the cation first and then the anion. In \(CaF_2\), the cation is calcium (\(Ca^{2+}\)) and the anion is fluoride (\(F^-\)). The suffix -ide is used for monatomic anions. So, the name is formed by combining the cation name (calcium) and the anion name (fluoride).

Answer:

calcium fluoride
