Chapter 2, Problem 19RQ

Summary Introduction

To analyze:

The following atoms ₆C¹², ₆C¹³, and ₆C¹⁴, and:

1. State the similarity in all of them.

2. The difference between them.

3. The definition for these groups of elements.

4. The atomic configuration of ₆C¹² showing relative positions and numbers of the subatomic particle by using the planetary model.

Introduction:

Atom is the smallest unit of any particle. When two elements combine with each other, the formation of molecules occurs. Molecules combine to form a molecular compound. An element is designated with the atomic number and atomic mass. An atomic number of an element is the number of protons of the element. Atomic mass can be defined as the summation of thenumber of protons as well as the neutrons present in the nucleus of the atom of the element.
