Answer:
Subatomic particles are the proton (1 amu), neutron (1 amu), and electron (0 amu)
Step-by-step explanation:
Atomic mass unit (amu; dalton): A unit of mass equal to exactly 1/12 the mass of one 12C atom, or 1.660538921 x 10−27 kg. This is the approximate mass of one proton or one neutron. It is the basis of atomic weights.
