Beta particles:
A)have a mass of 4 and a charge of +2
B)are like X-rays
C)are repelled by a positively charged plate
D)can be electrons
E)have the same mass as a neutron

Question

Quizplus · Accepted Answer

Beta particles can be electrons, which have a negative charge and a very small mass. They are emitted during beta decay in radioactive decay processes. A) is incorrect because a mass of 4 and a charge of +2 would describe an alpha particle. B) is incorrect because beta particles have mass and can be deflected by a magnetic field, whereas X-rays do not have mass and cannot be deflected by a magnetic field. C) is incorrect because beta particles are negatively charged and would be attracted to a positively charged plate. E) is incorrect because neutrons do not have an electric charge and do not emit beta particles during radioactive decay.
