Answer : The IUPAC name of the compound
will be calcium sulfide.
Explanation :
Ionic compound : It is defined as the compound which is formed when electron gets transferred from one atom to another atom.
Ionic compound are usually formed when a metal reacts with a non-metal.
The nomenclature of ionic compounds is given by:
- Positive ion is written first.
- The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
- In case of transition metals, the oxidation state are written in roman numerals in bracket in front of positive ions.
is an ionic compound because calcium element is a metal and sulfur element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.
Thus, the IUPAC name of the compound
will be calcium sulfide.
