In beta decays
A) a proton changes to a neutron.
B) a neutron changes to a proton.
C) an electron is present in the nucleus before the decay.
D) (a), (b) or (c) may occur.
E) only (a) or (b) may occur.

Question

Quizplus · Accepted Answer

Beta decay involves the transformation of a neutron into a proton (resulting in the emission of an electron), or the transformation of a proton into a neutron (resulting in the emission of a position or capture of an electron). Therefore, only options (a) or (b) may occur. Option (c) is not true, as electrons are not present in the nucleus.
