Answer:
atomic structure - The nucleus is at the center of an atom, where most of the charge and mass are concentrated
protons - a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign.
neutrons - a subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen.
electrons - a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.
atom vs. ion - an atom is the basic unit of a chemical element, and an ion is an atom or molecule with a net electric charge due to the loss or gain of one or more electrons. See also cation, anion.
Mass number - total number of protons, and neutrons in an atom.

Answer:
Explanation:
Milk and starch solution are example of colloidal solution and we know that Tyndall effect is shown by colloids.
P=m/V
m=40.24 g
V=50.0 mL=50.0 cm³
p=40.24/50.0=0.8048 g/cm³
I would say that if they would use the regular ones, they would not be able to see very far. as well with that i would add that they need special lenses to see far.
hope that this helps you! =)
