Chapter 4, Problem 8SAQ

Interpretation Introduction

Interpretation:

To find out the true statement abouteffective nuclear charge.

Concept introduction:

The total charge of all protons present in the nucleus is said to be nuclear charge. It has similar value as the atomic number.

Net charge experienced by the valence electrons is known as Effective nuclear charge. The electrons core is covered or shielded stronger than the outer valance of electrons. The atomic number will get increases and principle quantum number of an element will also increase and thus the atomic radius of an element will also get increases as we go down the group.
