Question

What name should be used for the ionic compound LiI?

Answer 1

Answer: The given compound is named as lithium iodide.

Explanation:

$LiI$ is an ionic compound because lithium is a metal and Iodine element is a non-metal.

We know that, a bond which is formed between a metal and a non-metal is always ionic in nature.

Ionic bond is formed when there is a complete transfer of electron from an electropositive element (a metal) to an electronegative element (non-metal).

The nomenclature of ionic compounds is given by:

1. Positive ion is always written first.
2. The negative ion is written next with a suffix added at the end of the negative ion. The suffix used is '-ide'.

Hence, the name given to $LiI$ will be lithium iodide.
