Proton Protons are sub-atomic particles which can be found in the nucleus.These have a positive charge and have 1 AMU.
Electron Electrons are sub-atomic particles which can be found on the orbital shells of the atom,These have a negative charge and have the smallest amount of AMU,1/1840
Neutron Neutrons are sub-atomic particles which can also be found inside the Nucleus.They have a neutral charge and have 1 AMU.
Atomic Mass Unit It is the unit used to measure the mass of a sub-atomic particle
Sub-Atomic Particle A sub-atomic particle make up an atom.There are 3 sub-atomic particles which make up an atom; 1.Protons 2.Electrons 3.Neutrons
