32.Alpha particles and beta particles differ in

Amass, only
Bcharge, only
Cboth mass and charge
Dneither mass nor charge

Verified Answer :

The answer is C.
Alpha particles are simply helium-4 nuclei, with 2 protons and 2 neutrons. Charge is 2+, and mass is on the order of 4amu. Beta particles are either electrons or positrons, with charges of 1- and 1+ respectively. Their masses are fractions of amu, so alpha particles and beta particles differ in both mass and charge.

the answer is C. both mass and charge  ;)
