Size of particles are very small (less than 1nm)

Size of particles are large (more than 100nm)

Size of particles is neither too small nor too large (1 - 100nm)

Individual Particles cannot be seen by the naked eyes

Particles of suspension can be seen by the naked eye

Particles of a colloid are too small to be seen by the naked eye

Particles are stable

they do not settle down when left undisturbed

Particles are not stable ,

 they settle down after some time

Particles are stable ,

 they do not settle down when left undisturbed

Particles of solution do not scatter light

Particles are large enough to scatter a beam of light

Particles are large enough to scatter a beam of light

Particles pass through filter paper, hence particles cannot be separated by filtration

Particles are large, they do no pass through filter paper, hence particles can be separated by filtration

Particles are small enough to pass through filter paper, hence particles cannot be separated by filtration
