Chapter 2, Problem 101AE

(a)

Interpretation Introduction

Interpretation:

From the given data, the corresponding elements and the number of each nucleons has to be found.

Concept introduction:

The smallest constituent of matter is atom.  Each atom consist of subatomic particles called electrons, protons and neutrons.  Protons and neutrons are present in the nucleus and called nucleons.  A group of atoms having same number of protons are called as an element.

The atomic symbol for an element can be represented as ${}_{\text{Z}}^{\text{A}}\text{X}$

Where $\text{X}$ represents the symbol of the element, $\text{Z}$ represents the atomic number of the element and $\text{A}$ represents the atomic mass or mass number of the element.

The atomic symbol for an element can be represented as ${}_{\text{Z}}^{\text{A}}\text{X}$

Where $\text{X}$ represents the symbol of the element, $\text{Z}$ represents the atomic number of the element and $\text{A}$ represents the atomic mass or mass number of the element.
