Answer:
An electron is a negatively charged subatomic particle. It can be either free (not attached to any atom), or bound to the nucleus of an atom. Electrons in atoms exist in spherical shells of various radii, representing energy levels. ... The charge on a single electron is considered as the unit electrical charge.
Atoms are made of extremely tiny particles called protons, neutrons, and electrons. ... Electrons surround the nucleus. Protons have a positive charge. Electrons have a negative charge. The charge on the proton and electron are exactly the same size but opposite.
