Chapter 9, Problem 38QRT

Interpretation Introduction

Interpretation:

The reason behind the difference in the melting point of $NaF$ and $MgO$ has to be explained.

Concept Introduction:

Coulomb’s law:

It states that the magnitude of the electrostatic force between two point charges is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them.

  $F=\frac{k{Q}_1{Q}_2}{r^2}$

Where, $k=$ Electrostatic constant.
