32.Alpha particles and beta particles differ in
A. mass, only
B. charge, only
C. both mass and charge
D. neither mass nor charge

Respuesta :

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  ;)
