Q1. Electrons can move easily from one atom to another. Why do eletrons move easily while protons don't?

Answer 1

For one thing, a proton is real heavy.(Compared to the electron.) So it's hard for them to move so freely.

Another thing is, inside an atom, the core consists of protons and neutrons. Electrons zoom around the core.

Q2. Find way in which static charges can be used in real life.
