Answer: The correct answer is mercury (ii) sulfide.

Step-by-step explanation:

Mercury is the 80th element of the periodic table and is considered as a metal. The oxidation state of this compound is +2.

Sulfur is the 16th element of the periodic table and is considered as a non-metal. The oxidation state of this compound is -2.

The compound formed when a metal and a non-metal reacts is ionic compound. Ionic compound is defined as the compound which is formed from the complete transfer of electrons from one atom to another.

The nomenclature of ionic compounds is given by:

  1. Positive ion is written first.
  2. If the positive ion is a d-block element, then the oxidation state is written as roman numerals.
  3. The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.

Hence, the name for HgS compound is mercury (ii) sulfide.
