Question

what is beta-decay? Thanks for helping

Answer 1

Atoms emit beta particles through a process known as beta decay. Beta particles are just electrons from the nucleus. A beta-decay occurs when there are too many protons or neutrons in a nucleus. It is a type of radioactive decay in which an electron is emitted. In the process, a neutron in the nucleus turns into a proton or vice-versa.

Hope this helps!

Answer 2

Beta decay:The radioactive decay in which high energy electrons are emittedfrom the nucleus of a radioactive atom is called beta decay. When a nucleus undergoes beta decay it transforms into a new nucleus after emitting a beta particle.Example:15P32--->16S32+-1e0-1e0is the beta particle of nuclear origin.In beta decay the atomic number of the new nucleus is more than the original nucleus but there is no change in mass number.
