Beta minus decay

In beta minus radioactive decay, beta minus radiation is emitted from the nucleus, and it has the equation:

^A_ZX\,\rightarrow\,\,^A_{Z+1}Y\,\,+\,\,^0_{-1}\beta\,\,+\,\,\overline\nu_e

Question	Answer
What is the particle emitted in beta minus decay and its symbol?	^0_{-1}\beta, a fast-moving electron.
What is the equation for beta minus decay?	^A_ZX\,\rightarrow\,^A_{Z+1}Y\,+\,^0_{-1}\beta\,+\,\overline\nu_e
What are the three products of beta minus decay?	^A_{Z+1}Y (a daughter nucleus), ^0_{-1}\beta (a beta particle/electron), and \overline\nu_e (an antineutrino).
How does the atomic number change in beta minus decay?	It increases by 1, from Z to Z+1.
How does the mass number change in beta minus decay?	It remains the same, A, because the emitted beta particle has negligible mass.
