Answer
D. gold sulfide
Explanation
## Step 1The naming of ionic compounds generally consists of the cation (the metal's name) and anion (a nonmetal with 'ide' ending). ## Step 2Gold can form ions with different charges, so its oxidation state is indicated in parentheses. ## Step 3In the compound AuS, gold exhibits a +1 oxidation state while sulfur has a -2 oxidation state. ## Step 4The ratio of gold to sulfur is 2:1, but this is not considered in the nomenclature. ## Step 5Therefore, the correct name for AuS is gold sulfide, without indicating any oxidation state.
