Paper 5, Paper 6
The nucleus remaining after a radioactive decay.
Revise: Nuclear decay mechanisms and equationsThe nucleus that decays is the parent nucleus; the nucleus left afterwards is the daughter nucleus. To describe what changes, we need to keep track of its protons and neutrons.
For beta decay, include the electron’s bottom number of −1: the daughter nucleus has an atomic number one higher, not one lower.
