Question

Q.26 the electrical nature of ionic and metallic solids in solid state respectively will be

Answer 1

Metals and ionic compounds both conduct electricity.

It is positive

Answer 2

Ionic solids act as electrical insulators in the solid-state while metallic solids act as electrical conductors in the solid-state:

Ionic solids:

• These solids are made up of ions like cations and anions that are bound together by strong electrostatic forces in a three-dimensional network.
• In this type of solid, the ions are not freely movable thus they cannot conduct electricity and act as electrical insulators in their solid state.

Metallic solids:

• These types of solids are made up of positively charged ions held together as well as surrounded by free negative electrons.
• The electrons are spread throughout the solid and are freely moving thus are able to conduct electricity making this type of solid electrical conductors in their solid state.

Thus, in their solid states, Ionic solids and Metallic solids act as electrical insulators and electrical conductors respectively.
