⇒ Our AZX notation is used to describe the nuclear reactions that happen during nuclear decay
⇒ During nuclear decay, there are two conservation rules that must be remembered:
⇒ What this means is that before and after the decay, the total value for A and Z remains the same i.e. the total nucleon number and proton number stay the same before and after the decay
⇒ If you have radium-226 and it decays, you will produce an alpha particle and the radioactive gas radon-222
⇒ If you have carbon-14and it decays, you will produce a beta particle, an antineutrino, and nitrogen-14:
