Question

Write symbolically the process expressing the β⁺ decay of `""_11^22Na`. Also write the basic nuclear process underlying this decay.

Answer 1

The β⁺ decay for `""_11^22Na` is given below:

`""_11^22Na->_10^22Ne+beta^++v`

If the unstable nucleus has excess protons than required for stability, a proton converts itself into a neutron. In the process, a positron e⁺ (or a β⁺) and a neutrino ν are created and emitted from the nucleus.

p→n+β⁺+ν

This process is called beta plus decay.
