Chapter 4, Problem 1IA.4Q

a.

Summary Introduction

To determine:

The representation of atoms that are black spheres in the ball-and-stick model.

Concept introduction:

Ball-and-stick model gives the three dimensional representation of molecular compounds. It clearly displays the bonds between the atoms and the atoms are represented by spheres.

Each chemical element is represented by spheres of different colors. In this model there is a good visualization of geometries that are difficult to see on paper. The bond lengths between the two atoms are represented by sticks and the atoms are represented by balls.
