True
False - Answers-False
If an atom contains more electrons than protons, the atom has a negative atomic
charge.
True
False - Answers-True
If two conductive materials in contact with each other are separated, most of the
electrons will return to the original surface before the separation is complete.
True
False - Answers-True
When insulated materials are in contact with each other, electrons move to the surface
of each other, but the protons remain on the original surface.
True
False - Answers-True
, When insulated bodies are quickly separated, both display an electrostatic charge
because one surface has an excess of electrons while the other surface has fewer
electrons.
True
False - Answers-True
Electrostatic charge is due to an excess of, or a deficiency of, electrons between objects
that have been separated.
True
