Chapter 4.8, Problem 4.81QAP

Interpretation Introduction

Interpretation:

The ionisation potential of an element depends on the last shell electron configuration of the element. The element which has low ionisation energy have more metallic character.

Concept Introduction:

The ionisation energy or Ionisation potential (I.P.) of an element is the energy required to remove the most loosely bound electron from free gaseous atom of the element in its ground state. This is expressed in ${\text{K J mol}}^{\text{-1}}$. Thus it can be shown as-$\text{A}\stackrel{\text{I}\text{.P}.}{\to }{\text{A}}^{\text{+}}$

To determine:

Fill the gap using higher or lower, more or less

Sr has a__________ ionisation energy and _________________ metallic character than Sb.
