There are a number of radioactive isotopes of copper, choosing 66Cu as on that undergoes negative beta decay, the equation is:
2966Cu --> 3066Zn + -10e
Where e represents the beta particle, which can also be viewed as an electron.
The equation for the beta decay of 14C: 614C --> 714N + -10e
where the -10e is the beta particle, represented as an electron.
The equation for the alpha decay of 239Pu is: 94239Pu --> 92235U + 24He
where 24He represents the alpha particle, which is a Helium nucleus.
Uranium-239 does NOT decay by alpha decay, it decays only by beta and gammadecay.
The first step is an alpha decay to (guess what!) uranium 235. You can probably take it from there.
The equation for the alpha decay of 222Rn is: 86222Rn --> 84218Po + 24He Where He represents the alpha particle, which can also be viewed as a Helium nucleus.
The equation for the beta decay of 137Cs is: 55137Cs --> 56137Ba + -10e where the -10e is a negative beta particle or electron.
All nuclear decay is spontaneous.
The equation for the alpha decay of 226Ra: 88226Ra --> 86222Rn + 24He The alpha particle is represented as a helium (He) nucleus.
Uranium-239 does NOT decay by alpha decay, it decays only by beta and gammadecay.
92Au 282Xe +13S
The equation for the alpha decay of 213At: 85213At --> 83209Bi + 24He where the alpha particle is represented as a helium nucleus.
The equation for the alpha decay of 265Bh is:107265Bh --> 105261Db + 24He where the 24He is an alpha particle or helium nucleus.
Plutonium-241 decays by both beta- and alpha decay. For beta- decay the equation is ...94241Pu -> 95241Am + e- + v-eNot asked but answered for completeness sake, for alpha decay the equation is ...94241Pu -> 92237U +24He2+
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.
The first step is an alpha decay to (guess what!) uranium 235. You can probably take it from there.
Th-230(alpha)Ra-226.
The equation for the alpha decay of 233U is: 92233U --> 90229Th + 24He representing the alpha particle as a helium nucleus. 223U can also undergo fission, but since this is an rather unpredictable process, there is no standard equation.
The equation for the alpha decay of 235U is: 92235U --> 90231Th + 24He representing the alpha particle as a helium nucleus. 235U also decays by spontaneous fission, but the results are somewhat unpredictable, so there is no standard equation.
