☆☆☆☆☆There are three beta decay modes for 40K, and so three equations.
The equation for the negative beta decay of 40K: 1940K --> 2040Ca + -10e
where the -10e represents a beta particle or electron.
The equation for the positive beta decay of 40K: 1940K --> 1840Ar+ 10e
where the 10e represents a positive beta particle or positron.
The equation for the decay of 40K by electron capture is:1940K + -10e --> 1840Ar + ve
