Several differences:
Electrons are NOT part of the nucleus of an atom, they only encircle it, typically called the electron cloud. Electrons are also negatively charged.
Protons carry a positive charge and are found in the nucleus with neutrons. Neutrons have no electrostatic charge, hence their name.
Furthermore,
Protons contribute to the Atomic Mass as well as represent each element by its atomic number (i.e. atomic number = # protons). The number of neutrons in an atom's nucleus corresponds to the elements isotope, or "version" of the same element. A different isotope number changes the Atomic Mass (and also sometimes its radioactivity). Electrons on the other hand, contribute electrostatically to elemental interactions and in forming bonds, since these entities are found in the outermost parts of an atom (i.e. in the cloud surrounding the nucleus). Additionally, electrons can be dropped or elevated in their energy states through various ionization energies that can contribute to various atomic activities, such those of certain gases. Some common examples are the Mercury (energy saving) light bulbs, and neon lighting signs.
Cl-37 : 17 protons , 20 neutrons , 17 electrons Compare with Cl-35 ; 17 protons , 18 neutrons, 17 electrons. These are two different and common isotopes of chlorine. Remember 'Different isotopes have a different number of neutrons'. Chemically they react the same.
