Question

1.Element - settles down on standing
2. Compound Impure substance
3. Colloid - Made up of molecules
4. Suspension Pure substance
5. Mixture - Made up of atoms​

Answer 1

suspension is a heterogeneous mixture in which some of the particles settle out of the mixture upon standing. The particles in a suspension are far larger than those of a solution, so gravity is able to pull them down out of the dispersion medium (water).
