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

Which nuclear reaction is classified as alpha decay?

The equation for the alpha decay of 210Po is:84210Po --> 82206Pb + 24He where He represents the alpha particle, which can also be viewed as a Helium nucleus.


What is the nuclear decay equation for copper 64?

Cu decays by either negative or positive beta emission. The equation for the negative beta decay of 64Cu is: 2964Cu --> 3064Zn + -10e where -10e represents a negative beta particle or electron. The equation for the positive beta decay of 64Cu is: 2964Cu --> 2864Ni + 10e where 10e represents a positive beta particle or positron.


What is the nuclear decay equation for hydrogen-hydrogen?

The only hydrogen isotope that undergoes any type of radioactive decay is tritium (hydrogen-3), it undergoes beta decay to become helium-3. If that's not what you were asking about, I'm confused by your question.
