Properties of Subatomic Particles
-Subatomic particles is a particle smaller than an atom

Ex: proton, neutron, and electrons
-Ernest Rutherford discovered the proton particle in the nucleus, and each proton has +1 charge.
-Joseph Thomson detected electron particles outside of the nucleus, and its charge has a -1 charge.
-James Chadwick designed an experiment that showed neutrons exist. -----Chadwick concluded that the
particles were neutral because a charge object did not deflect their path. A neutron is found inside the
nucleus as well.
Comparing Subatomic Particles

Subatomic particles can be distinguish by mass, location, and charge
