Question

What type of solids are electrical conductors, malleable and ductile?

Answer 1

Hint: In order to know which type of solids are electrical conductor, malleable and ductile, we must be knowing what are the different types of solids present and the different characteristics of different types of solids.

Complete step by step answer:
- First, let us understand what a solid is. Solids is a substance with definite shape and mass. It will be having a tightly packed structure. The solids will have definite volume. The force of attraction present in a solid is very strong.
- On the basis of arrangement in the solid, it can be classified into two types;
- Crystalline solid
- Amorphous solid.
- Crystalline solids are the solids which have a definite three-dimensional structure. The crystalline structure is classified into further four types, they are;
- Molecular solid
- ionic solid
- Covalent solid
- Metallic solid.
- Let us now see the metallic solids in detail.
- Metallic solids are the solids which are formed by metallic bonds. The metallic bond is a force of attraction present in the solid which can bind the positive ion (i.e. the cation) with the freely moving electrons present in the crystal structure.
- Metallic solids will be having the following characteristics such as
- It will be having good thermal conductivity.
- Good electrical conductivity.
- It has a good lustrous property.
- It will have a high melting point and high boiling point.
- It is highly malleable and ductile.
- They have sonorous property.
Therefore, the type of solids which are electrical conductors, malleable and ductile is metallic solids.

Note: Comparison between crystalline solids and amorphous solids.

CRYSTALLINE SOLIDS	AMORPHOUS SOLIDS
It has regular internal arrangement of particles.	It has irregular internal arrangement of particles
It is anisotropic	It is isotropic.
They are true solids.	They are supercooled liquids.
They have definite shapes.	They do not have definite shapes.
