hope it is correct and helpful to you✌

Answer 2

Particle don't settle down is the correct answer.

Colloidal particles do not settle down, they always remain suspended.

For example- Pure Milk is a colloid.

We don't see anything at the bottom of a glass of pure milk.

Reasons-

1) Colloidal particles show tyndall effect

2Colloidal particle size range from 1 to 1000 nm.It cannot be greater than that.

4) Colloidal particles cannot be separated by simple physical method .

One complex method known as centrifugation is required for separating its constituents.
