# Write the Basic Nuclear Process Underlying this Decay - Physics

#### Question

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

#### Solution

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.

pn+β++ν

This process is called beta plus decay.

Is there an error in this question or solution?
