Alpha particles have a charge of +2 and a mass of 4
Gamma rays have a charge of 0 and a mass of 0
Neutrons have a charge of 0 and a mass of 1
Beta positrons have a charge of +1 and a mass of 0
The neutrino is the particle that cannot be accelerated in a
magnetic field.
To add, a neutrino is a subatomic particle that is
very similar to an electron, but has no electrical charge and a very small
mass, which might even be zero.
The colored light emitted is energy and in order to emit energy the element should first obtain energy. The energy absorbed by the substance can be in the form of radiation, heat or electricity. Hope this answers the question. Have a nice day.
