== == 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.

When radium-226 decays to form radon-222 the radium nucleus emits a?
When Radium-226 decays to form Radon-222, the Radium nucleus emits an alpha particle. The atomic number goes down by 2, and the mass number goes down by 4, matching the atomic number and mass number of the alpha particle.
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 beta decay of radium 226?
Radium-226 does not decay by beta decay. It decays by alpha decay to radon-222.
What type of radiation does Radon give off?
Naturally occuring Radon gas decays by alpha particle emission. However, many of the decay chain products have very short half lives, of which some decay by alpha particle emission and others by beta particle emission.
What new element is formed when radium decays?
The neutrons aren't really relevant, since we don't know what the mass of the radium nucleus was and the element is determined strictly by the number of protons anyway. Radium has an atomic number of 88; losing 4 protons would make the atomic number 84, which is polonium. (This is probably really a two-step process: radium -> radon -> polonium, where each step is an alpha decay.)
What dangerous gas is produced when radium decays?
Radon
When radium -226 decays to form radon -222 the radium nucleus emits?
When radium-226 decays to form radon-222, the radium nucleus emits a alpha particle.
What gas is produced when radium decays?
The extremely dangerous Radon (my favorite element).
When radium-226 decays to form radon-222 the radium nucleus emits a?
When Radium-226 decays to form Radon-222, the Radium nucleus emits an alpha particle. The atomic number goes down by 2, and the mass number goes down by 4, matching the atomic number and mass number of the alpha particle.
Why is radon gas poisonus?
Radon gas, if it decays in a person's lungs, leaves material that stays in the lungs, decaying repeatedly and quickly. It is very radioactive, and can cause cancer.
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 beta decay of radium 226?
Radium-226 does not decay by beta decay. It decays by alpha decay to radon-222.

Does radon gas give off alpha radiation?
Yes it does. By the time a radon nucleus has decayed to a stable lead nucleus 6 alpha particles have been emitted. These are dangerous to health. For this reason, basements which are in high radon areas should be positively vented to the outside. Note. care should be taken with decorative granite counter-tops. Some of these cause radon levels in the kitchen which are far above the safe limit.
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 effect does krypton have on nature?
like radon, krypton kills and affects most plants and animals. It has harmful chemicals that affect the Thyroid glands in most humans and decays plant lives in nature. krypton is found in tap water. It also causes cancers and thyroid disease. you can purchase kyrypton and radon kits from your local hardware store or from fema
