Interpretation Introduction

Interpretation:

The property of metals being good conductors of heat and electricity has to be explained.

The decrease in electrical conductivity of metals with increase in temperature has to be reasoned.

Concept Introduction:

In the periodic classification of elements, metals are located in the group IA, IIA, IB to VIIIB. Group IA and IIA elements are known as Alkali metals and alkaline earth metals respectively. They constitute s-block elements. Group IB to VIIIB elements constitute d-block elements.

Metals are known to be good conductors of heat and electricity. Metals exist as solids called Metallic solids. Metallic solid is a typical crystalline solid where metal exist as metal ions by losing their valence electrons. Those valence electrons are termed as free electrons which are delocalized throughout the metal lattice.
