Chapter 21, Problem 21.73QP

Interpretation Introduction

Interpretation:

The change in metallic character of the main group elements as we move from left to right of the periodic table and as we move down the periodic table has to be explained.

Concept Introduction:

Metallic character of any element refers to the electropositivity of the element.  The term electropositivity refers to the tendency of an element to lose its valence electrons readily under reaction conditions.

Greater the electropositivity of an element, more is its metallic character.
