A detector records two successive emissions in a decay chain.
The parent nucleus has mass number 237 and atomic number 93. It emits alpha radiation. The daughter nucleus then emits beta-minus radiation.
Complete the Table.
| Nucleus in the decay chain | Radiation just emitted | Mass number | Atomic number |
|---|---|---|---|
| parent nucleus | none | 237 | 93 |
| first daughter nucleus | alpha | ||
| second daughter nucleus | beta minus |
Explain, in terms of changes to the particles in the nucleus, the mass number and atomic number you calculated for the second daughter nucleus.
