(a)

Interpretation Introduction

Interpretation: Electron dot structure for an atom of Carbon needs to be determined.

Concept introduction: Electron dot structure represents the valence electrons around the elements. The electrons are denoted as dots around the symbol of the element.

Answer to Problem 90A

Carbon $\left[\text{H}\text{e}\right]2{\text{s}}^{2}2{\text{p}}^2$

Explanation of Solution

Electron dot structure for an atom is a representation of the valence shell electrons in an atom. It shows how the electrons are arranged around the atom. Electrons are presented as dots around the symbol of element.
