Chapter 7, Problem 30Q

Interpretation Introduction

Interpretation:

The reason for the properties such as size, ionization energy and electron affinity hold good for diagonal relationship in periodic table is to be given.

Concept introduction:

Diagonal effect in a periodic table is the phenomenon which gives the chemical similarities between the lightest element of one group and the element immediately below and to the right of it in the next group.

To determine: The explanation that diagonal relationships hold for properties such as atomic size, ionization energy and electron affinity in descending down the group and moving along the period.
