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
The equation for the beta decay of 42K:
1942K --> 2042Ca + -10e
where the e is an electron or beta particle.
4019K - 0-1e = 4020Ca
(sorry, best I could write it on a computer :S)
The equation for the beta decay of 87Kr is:
3687Kr --> 3787Rb + -10e
where -10e represents a negative beta particle or electron.
The equation for the beta decay of 86Rb:3786Rb --> 3886Sr+ -10e where the -10e represents a beta particle or electron.

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.
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.
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.
All nuclear decay is spontaneous.
Natural chromium is stable and does not decay/
Energy and electrical charge are two quantities that are always conserved in nuclear decay equation.
The decay equation is:Co-60----------------------Ni-60 + e-
The equation for the beta decay of 14C: 614C --> 714N + -10e where the e is an electron.
T99 is Technetion 99 has a Decay rate of 6h
The equation for the alpha decay of 226Ra: 88226Ra --> 86222Rn + 24He The alpha particle is represented as a helium (He) nucleus.
