Chapter 2, Problem 3WIO

Summary Introduction

To draw:

The electron shells of the given atoms and predict the number of bonds each atom should form.

Introduction:

Electrons occupy distinct energetic regions around the nucleus. They are constantly in motion, so it is not possible to detect the exact location of an electron at a given moment. The electrons can be imagined as occupying a series of concentric energy shells. Each shell has a higher energy level than the one inside it.
