Question

which statement describes how the binary ionic compound kbr is named?
○ the nonmetal is named first, and the name is unchanged.
○ the metal is named first, and the name is unchanged.
○ the nonmetal is named second, and the name is unchanged.
○ the metal is named second, and the name is unchanged.

Explanation:

For binary ionic compounds, the naming rule is to first name the cation (metal, from potassium, K, here) using its elemental name unchanged, then name the anion (nonmetal, bromine, Br) by modifying its ending to "-ide" (bromide). This matches the correct option.

Answer:

The metal is named first, and the name is unchanged.
