Question

Lewis structure of Li is _____

• A.
• B.
• C.
• D. None of these

Answer 1

The correct option is C

In Lewis structure, the nucleus along with the inner electrons are together termed as kernel which are not depicted.Only valence electrons are to be shown.

Li = 1$s^2$ 2 $s^1$ .Thus the 1s $e^{-}$s are a part of kernel,therefore only one electron will be shown along with the symbol of the element.
