Is radon-222 an earth mineral?
No, Radon is an element. 222Rn belongs to the radium and uranium-238 decay chain, and has a half-life of 3.8235 days.
How many days are required for 200 grams of radon 222 to decay to 50.0 grams?
Radon-222 has a half-life of about 3.8 days. To calculate the time required for 200 grams of radon-222 to decay to 50 grams, you can use the formula: [N = N_0 \left(\frac{1}{2}\right)^{\frac{t}{t_{1/2}}}] where N is the final amount (50 grams), N0 is the initial amount (200 grams), t is the time in days, and t1/2 is the half-life. Solving for t gives around 7.6 days.
Is radon 222 unstable or stable?
no because it is so radioative its so unstable.
Hyphen notation for Radon?
The hyphen notation for Radon is Rn-222.
How long does it take for 60 of a gas radon to decay when it has a half life of 3.82 days?
Half-life time of a radioactive element is the time required for the decomposition of half of the actual mass of the element."Half life of radon is 3.8 days."This means that a particular mass of radon is reduced to half its mass in 3.8 days. The half-life period of an element does not depend upon the original mass of the element. This means that 10gms of radon will become 5gms of radon is 3.8 days, and 80gms of radon will become 40gms in 3.8 days.
The half-life of radon - 222 is 3.823 days. What is the length of 4- half-lives?
The length of four half-lives of radon-222 can be calculated by multiplying the half-life duration by four. Since the half-life of radon-222 is 3.823 days, four half-lives would be 4 × 3.823 days, which equals approximately 15.292 days.
How many days are required for 200 grams of radon-222 to decay to 50 grams?
7.64 it is the half life of radon-222 multipled by 2

Will a sample of radon-222 eventually all disappear?
Maybe, and maybe not. It depends on how large the sample is and how long "eventually" is. Though radon has a modest half-life, it still takes a long, long time for any appreciable amount to decay to the point where we can't detect it. Remember that any "sample" will contain radon atoms numbered in many powers of ten. Then there's the fact that a half-life is a statistically derived amount of time, meaning that a single given atom or a small number of atoms won't "obey" the "rule" of the half-life and decay "on schedule" per the time cited. All the atoms of radon-222 may not disappear "eventually" as was asked. But for all practical purposes, a sample might be said to disappear over geologic time. Radon-222, an isotope of the radioactive inert gas, has a half-life of 3.8235 days. That means that in 3.8235 days, half of the 222Rn sample will be gone. In another 3.8235 days, half of that remaining 222Rn will be gone. And so on. Note that the radon-222 is undergoing radioactive decay to "disappear" as was asked. Additionally, each radon-222 atom that decays will have to undergo another 7 decay events to become a stable isotope of lead. And all of this is radioactive decay.
How long will it take for 30g of radon-222 to decay to 7.5g?
Radon-222 has a half-life of about 3.8 days. To calculate the time it will take for 30g to decay to 7.5g, you can use the radioactive decay equation: final amount = initial amount * (1/2)^(t/h), where t is the time and h is the half-life. Solving for t gives approximately 7.6 days.

Which elements atomic mass is 222 amu?
The element with an atomic mass of 222 amu is radon (Rn).
Is radon 222 an indoor particle?
Radon-222 is a radioactive gas that is a natural byproduct of the decay of uranium in soil and rocks. It can seep into buildings through cracks in foundations and accumulate indoors. While not a particle itself, radon-222 can decay into solid radioactive particles called radon progeny, which can pose health risks when inhaled.
What are the isotopes of radon?
There's just the one, and it's 222Rn, or radon-222. There might be a trace of some of the other isotopes around if there has been a nuclear accident or the like, but it is unlikely that they could be detected unless the accident was huge, had just occurred and you were testing right on top of it.
