Chapter 2, Problem 2.79QP

1. a)

Interpretation Introduction

Interpretation: The neutron numbers to be predicted for the given element symbols

Concept Introduction:

Conversion of atoms to moles: $\text{no}\text{.of moles = }\frac{\text{no}\text{.of atoms}}{\text{Avogadro's number}}.$

Nuclear stability: The nucleus is composed of protons and neutrons. The strongest nuclear force binds the particles tightly. Though the protons repel each other due to no attraction between similar charges, possess short-range attractions made the attraction possible between proton and proton, proton and neutron, neutron and neutron.

The stability of any element is determined by the difference between columbic repulsion and the short-range attraction. If repulsion outweighs the attraction, the disintegration of nucleus occurs by producing the daughter nuclides. If the attractive forces prevail, the nucleus is stable.

The stability of any element is determined by the difference between coulombic repulsion and the short-range attraction. If repulsion outweighs the attraction, the disintegration of nucleus occurs by producing the daughter nuclides. If the attractive forces prevail, the nucleus is stable.
