Question

Which of the following is a correct representation of lewis dot structure of lithium?

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

In lewis symbol, the nucleus and the inner shell electrons are represented by the symbol of the element. While, the valence electrons are represented as dots around the symbol of the element.

The electronic configuration of lithium is 1$s^2$ $2s^1$. Thus, it has only one valence electron which will be depicted by a dot around the symbol of lithium.
