Question

What is the diagonal relationship?

Answer 1

Introduction

• In S block elements, there is a diagonal link between adjacent elements in the second and third periods of the periodic table.
• When compared to the other components in the sub-group to which they belong, the attributes of s block elements differ dramatically.

Points to remember

• The diagonal neighbors have a lot in common.
• As you proceed from left to right and along with the group there will be a noticeable change in their relationship.
• Many atomic properties change in distinct ways down groups and across periods of the Periodic Table, resulting in diagonal correlations.
• The elements of the s and p-block elements have diagonal relationships in addition to group and period relationships.

Explanation

• The elements show some similarities when going diagonally across the periodic table, but they are far less evident than the similarities within a group.
• In the second and third periods of the periodic table, the diagonal relationship is most visible.

The diagonal relationship is owing to the diagonally positioned components having identical polarising power.
