The valence electrons are usually represented as dots around the elemental symbol. It is a two-dimensional way of representing the structural formula. Visit BYJU'S to know more about it.
Have students use bingo daubers as they race to create Lewis dot structures for elements.

A Lewis Structure is a simplified representation of the valence shell electrons in a molecule. There are two hydrogen atoms, one carbon atom, and one oxygen atom in the CH2O lewis structure. The oxygen and carbon atoms have a double bond.

So Moorcock really hates sentimental prose, and it can’t be because these authors or their books are conservative. That appears to be a justification Moorcock invented to look altruistic. So what’s his deal? What Moorcock Actually Cares About ...
