Question

1.compare the properties of metal and nonmetals with respect to : (i) malleability (ii)ductility and(iii) conduction of heat and electricity.
Ans= ​

Answer 1

Answer:

The property of metals which allows metals to be hammered into thin sheets is called Malleability. Due this unique property, metals can be flattened into thin sheets by hammering and rolling.

The property of metals which enables them to be drawn into wires is called Ductility. Due to this property metals can be stretched without breaking and drawn into thin wires. For example, Aluminium and copper are examples of highly ductile metals.

Metals have free electrons which makes them good conductors of heat and electricity. Non- metals do not have free electrons, hence, they are nonconductors of heat and electricity.

Answer 2

Answer:

metals are highly malleable and ductile

non metals are not malleable and ductile

metal are good thermal as well as electrical conducter.non metal are insulator except graphite
