A photon is an elementary particle, the quantum of all forms of electromagnetic radiation including light
amu
The unified atomic mass unit or dalton is the standard unit that is used for indicating mass on an atomic or molecular scale
neutron
The neutron is a subatomic particle, symbol n or n0, with no net electric charge and a mass slightly larger than that of a proton
quantum number
Quantum numbers describe values of conserved quantities in the dynamics of a quantum system
spin quantum number
In atomic physics, the spin quantum number is a quantum number that parameterizes the intrinsic angular momentum of a given particle
subatomic particles
In the physical sciences, subatomic particles are particles much smaller than atoms
