What is the size range of colloidal particles?

What is the size range of colloidal particles? Correct Answer 10-7 to 10-5 cm

A colloidal solution has particles in it in the range of 1nm to 1μm in size which is larger than most ordinary molecules but still way too small to be seen by the naked eyes. In centimeters the particle size ranges between 10-7 to 10-5 cm.

The critical reasoning question is based on a short argument, a set of statements, or a plan of action. For each question, select the best answer of the choices given. The size of particles is directly linked to their potential for causing health problems. Small particles less than 10 micrometers in diameter cause the greatest problems, as they can get deep into the lungs and some may get into the bloodstream. One being exposed to such particles can affect both the lungs and the heart of a person.
