Answer
α-particle
Consists of two electrons and two neutrons and are positively charge particles.
Cathode rays
A stream of electrons which is observed in a vacuum and made of negatively charge particles.
Proton
Positively charged particle in the nucleus.
Neutron
These are the electrically neutral particles which have-slightly larger mass than proton.
Electron
Negatively charge particle which lie in circular orbits around the nucleus.
