Describe the structure of an atom

Atoms consist of 3 particles: protons, electrons, and neutrons. The nucleus of the atom contains the protons and neutrons. The outer regions contain the electrons

Explanation:

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
