1- 218 Po if emits one alpha and two beta particles it becomes 214 Po
2- 214 Po if emits one alpha and two beta particles it becomes 210 Po.
This is all hypothetical.
Radon-222 undergoes alpha decay to produce polonium-218as a daughter.
Since an alpha particle is a helium-4 nucleus, the resulting atom has an atomic mass that is 4 less, so 226 minus 4. Also, to get the element, look up the element number for radium, and subtract two from that.
== == 222Rn is the only natural isotope of radon. (Several other artificial isotopes are known, but about the only place they exist is in the physics lab. Let's work with the natural one.) This isotope is itself the daughter of 226Radium, by the way. (226Ra had to decay to create 222Rn.) The decay scheme for radon is as follows: 222Rn will alpha decay (half life of 3.8 days) into 218Po 218Po will alpha decay (half life of 3.1 minutes) into 214Pb 214Pb will beta decay (half life of 27 minutes) into 214Bi 214Bi will beta decay (half life of 20 minutes) into 214Po 214Po will alpha decay (half life of 160 microseconds) into 210Pb 210Pb will beta decay (half life of 22 years) into 210Bi 210Bi will beta decay (half life of 5 days) into 210Po 210Po will alpha decay (half life of 138 days) into 206Pb (stable) In case it isn't obvious, radon and its daughters are all radioactive and pose a hazard. (Save lead, 206Pb, the final daughter.) And because radon is a gasand is inert, it travels around in the air and can be inhaled. And an airborne radionuclide is harder to defend against and contain than a liquid or solid one. Radon is suspected of accounting for a high percentage of lung cancer deaths since exposure to radiation can cause cancer. What really sucks is that if you breathe in a radon atom and it decays in your lungs, it changes into a polonium atom while irratiating you. You probably can't get rid of the polonium atom (it's a metallic solid), and it is also radioactive. An atom of radon must undergo 8radioactive decay events to get to a stable isotope of lead. That means if a radon atom you inhale decays, you get that shot of radiation, and you will probably get 7 more shots of radiation - in the same general location - before things are over. Lots of biological damage can occur. And these decay events involve some very damaging particulate radiation (alpha and beta radiation). It's about the worst of the worst.

The equation for the alpha decay of 210Po is: 84210Po --> 82206Pb + 24He representing the alpha particle as a helium nucleus. 206Pb, the daughter atom, is stable.

Beta Decay.
If radon-210 undergoes alpha decay, it will produce the alpha particle (which is a helium-4 nucleus) and polonium-206. The equation looks like this: 86210Ra => 24He + 84206Po You'll note that in the balanced nuclear equation, the atomic numbers, which are the subscripts, balance on both sides of the equation (86 = 2 + 84). The atomic masses, which are the superscripts, also balance on both sides of the equation (210 = 4 + 206).
Through natural or facilitated decay processes.
The equation for the alpha decay of 210Po is: 84210Po --> 82206Pb + 24He representing the alpha particle as a helium nucleus. 206Pb, the daughter atom, is stable.
