A computer simulation gives the mass number and atomic number of a nucleus before and after it emits radiation.
The result for alpha emission is complete.
| Radiation emitted | Parent mass number | Parent atomic number | Daughter mass number | Daughter atomic number |
|---|---|---|---|---|
| alpha | 196 | 78 | 192 | 76 |
| beta minus | 63 | 28 | 63 | |
| beta plus | 26 | 13 | 26 | |
| gamma | 115 | 49 | 49 | |
| neutron | 89 | 36 | 36 |
Complete the Table.
A proton-rich nucleus emits a positron.
Explain how this emission affects the mass number and the element of the daughter nucleus.
