spell out the full name of the compound.
name:

Explanation:

Step1: Identify ions

The formula is $CaF_2$. Calcium ($Ca$) forms $Ca^{2+}$ ion. Fluorine ($F$) forms $F^-$ ion.

Step2: Name ionic compound

For ionic compounds, name the cation first (Calcium), then the anion. The anion $F^-$ is named fluoride. Since there are two fluoride ions (from the subscript 2 in $F_2$), but we use the name of the anion with -ide suffix. So combine them: Calcium fluoride.

Answer:

Calcium fluoride
