During beta decay, which particle is emitted from the nucleus?
A
An alpha particle
B
An electron (beta minus particle)
C
A proton
D
A neutron
Verified step by step guidance1
Understand that beta decay is a type of radioactive decay where a nucleus emits a beta particle to transform into a different element or isotope.
Recall that in beta minus decay, a neutron inside the nucleus is converted into a proton, and this process emits a beta particle.
Recognize that the beta particle emitted during beta minus decay is an electron, which is ejected from the nucleus.
Note that an alpha particle consists of 2 protons and 2 neutrons and is emitted during alpha decay, not beta decay.
Conclude that during beta minus decay, the emitted particle is an electron (also called a beta minus particle).
