Beta decay
A beta particle forms when a neutron changes into a proton and a high-energy electron. The proton stays in the nucleus but the electron leaves the atom as a beta particle. When a nucleus emits a beta particle, these changes happen:
the mass number stays the same
the atomic number increases by 1
the nuclear charge increases by 1
