2) No. Some of the electrons are free to move from atom to atom as a result of friction, but the nuclei are not.
3) yes

how can you charge an object negatively with only the help of a positively charged object?
-This one I am not too sure,
when one material is rubbed against another electrons jump readily from one to the other but protons do not. why is this? (think in atomic terms)
-Is it because they are in an excited state
how do electrical field lines indicate the strength of an electric field?
-The closer they are together, the stronger the electric field.
