Question

Which is a property of most nonmetallic solids?

(1) high thermal conductivity(2) high electrical conductivity(3) brittleness(4) malleability

Answer 1

Most nonmetallic solids have the property of brittleness.

Answer 2

Answer : The correct option is, (3) brittleness

Explanation :

The properties of nonmetallic solids are :

• Nonmetallic solids are brittle in nature.
• They are non-malleable and ductile.
• Nonmetallic has low thermal conductivity. That means they are poor conductor of electricity.
• Nonmetallic has low electrical conductivity. That means they are poor conductor of heat.
• They are non-lustrous.
• The melting point and boiling point of non metals are lower than the metals.

Hence, the brittleness is a property of most nonmetallic solids
