The most radioactive isotope known to date is Californium-252.
Argon-40 is the most commonly found isotope of argon on Earth, with a natural abundance of about 99.6%. This isotope is stable and is produced from the radioactive decay of potassium-40 in the Earth's crust.
Potassium is the most radioactive among lithium, sodium, and potassium. Potassium has a naturally occurring radioactive isotope, potassium-40, which is present in all potassium samples and contributes to its radioactivity.
Europium is radioactive, though for most practical purposes it can be treated as stable. 52.2% of europium is stable. 47.8%, is radioactive 151Eu, but the half life of this is long, at 5,000,000,000,000,000,000 years. Like all other elements, europium has radioactive synthetic isotopes.
Tritium (pronounced /ˈtrɪtiəm/ or /ˈtrɪʃiəm/, symbol T or 3H, also known as Hydrogen-3) is a radioactive isotope of hydrogen. The nucleus of tritium (sometimes called a triton) contains one proton and two neutrons, whereas the nucleus of protium (the most abundant hydrogen isotope) contains one proton and no neutrons. Tritium is extremely rare. The isotope name is formed from the Greek meaning "third"
Holmium actually has the highest magnetic strength out of all known elements given it is first submersed in an artificially produced magnetic field.
An isotope of cobalt is used to to kill cancer cells. The isotope americium-241 is used in smoke detectors.
Radon-222 is the most harmful isotope of radon. It is radioactive and decays into other radioactive elements called radon progeny, which can attach to dust particles and be inhaled, increasing the risk of lung cancer.
Carbon-14 is the isotope most commonly used in radioactive dating of organic materials like bones and charcoal.
Carbon 14... i just did that same question on castle learning haha :)
No, Barium has both stable and radioactive isotopes. Out of its 25 known isotopes, only 6 of them are considered radioactive. The most stable isotope of Barium is Barium-138, which is not radioactive.
carbon-14
Yes.......most likely. I can't think of anything to do with Uranium, that isn't radioactive! -------- Uranium natural isotopes are not so radioactive compared with other isotopes; but all the isotopes of uranium are radioactive.
No. The most common isotope(s) of an element are often stable.
Sodium primarily exists as stable sodium-23, which is the most common and stable isotope of sodium. However, sodium can also form radioactive isotopes, with sodium-22 being a well-known example that is radioactive.
Argon-40 is the most commonly found isotope of argon on Earth, with a natural abundance of about 99.6%. This isotope is stable and is produced from the radioactive decay of potassium-40 in the Earth's crust.
Hydrogen has only one natural radioactive isotope(3H), of cosmogenic origin, but only in ultratraces on the earth. Sodium has two radioactive natural isotopes (22Na and 24Na), of cosmogenic origin, but only in ultratraces on the earth. Oxygen has not natural radioactive isotopes. All the isotopes of uranium are radioactive.
Carbon-12 is the most common isotope of carbon, with 6 protons and 6 neutrons. Carbon-14 is a radioactive isotope of carbon with 6 protons and 8 neutrons, commonly used in radiocarbon dating to determine the age of organic materials.
