What occurs during beta decay?

Back

In beta decay, a neutron is converted into a proton and an electron, with the electron being emitted as a beta particle.

What is nuclear fission?

Back

Nuclear fission is a nuclear reaction in which a heavy nucleus splits into two or more lighter nuclei, along with the release of energy.
