When a radon 222 nucleus decays what is the other product that forms?
Radon-222 undergoes alpha decay to produce polonium-218as a daughter.
What is the nuclear reaction for alpha decay of Radium-226?
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.
What decays producing radon?
== == 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.
What is the balanced reaction for the predominant method of decay of radon?
In the case of Rn-222, which is the "isotope of concern" because it occurs naturally, it decays as follows: 222Rn => 218Po + He+2 In this equation, we see the radon isotope Rn-222 emit an alpha particle (the helium nucleus) and undergo a transformation to become the polonium isotope, Po-218.

What is the nuclear decay equation for uranium-238 to strontium-90?
The equation for the beta decay of 87Kr is: 3687Kr --> 3787Rb + -10e where -10e represents a negative beta particle or electron.

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 mass converted to in nuclear processes?
nuclear decay, such as alpha decay or beta decay.
What radioactive decay processes do not reduce the atomic number of a nuclide?
Isomeric transition and internal conversion are examples of radioactive decay processes that do not reduce the atomic number of a nuclide. These processes involve the reorganization of the nucleus rather than changing the number of protons in the atom.
What equation correctly represents alpha decay of polonium 214?
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.
Are there any non examples of radioactive decay?
Nuclear fusion and nuclear fission are processes that involve nuclear reactions but are not examples of radioactive decay. Chemical reactions, such as burning wood, do not involve nuclear processes and are also not examples of radioactive decay.
