Chapter 8, Problem 8.136QP

Interpretation Introduction

Interpretation:

An account on the importance of the periodic table has to be written.

Concept Introduction:

According to physical and chemical properties, the elements can be further divided into metals, non-metals and metalloids.In a group, the metallic character of an element increases from top to bottom whereas in a period, it decreases from left to right.

Atomic radius is the distance between the atomic nucleus and outermost shell having electrons of an atom. From the atomic radius, the size of atoms can be visualized

The ionization energy is the minimum energy required to remove the electron from an isolated atom which is in the gaseous state results to give gaseous ion with one positive charge.

Effective nuclear charge $Z_{\text{eff}}$ is the net nuclear charge experienced by an electron when the whole nuclear charge and the shielding of other electrons are considered.

The periodic table is given below:
