Which statement describes how the binary ionic compound kbr is named?
a. the nonmetal is named first, and the name is unchanged.
b. the metal is named first, and the name is unchanged.
c. the nonmetal is named second, and the name is unchanged.
d. the metal is named second, and the name is unchanged.

The correct option is B.

Ionic compounds are made up of metals and non metals, which are joined together by mean of electrovalent bond, which involves donation and acceptance of electrons. When it comes to giving names to ionic compounds, the metal content of the compounds usually come first. For instance, for the question given above, the name of the ionic compound is Potassium bromide. Potassium is a metal while bromine is a non metal. You will notice that, the metal portion of the compound comes first and then the non metal part. The non metal part always end with 'ide'.
