Solution Steps
Step 1: Identify the Elements in the Compound
The compound given is BaS. It consists of two elements: barium (Ba) and sulfur (S).
Step 2: Determine the Oxidation States
Barium is an alkaline earth metal and typically has an oxidation state of +2. Sulfur, in this compound, will have an oxidation state of -2 to balance the +2 charge from barium.
Step 3: Name the Compound
The systematic name of an ionic compound is formed by naming the cation (positive ion) first, followed by the anion (negative ion). The cation, barium, retains its elemental name, and the anion, sulfur, is named as "sulfide."
Final Answer
The systematic name for BaS is \(\boxed{\text{barium sulfide}}\).
