What is a colorless naturally occurring radioactive inert gaseous element formed by radioactive decay?
It is radon that we see formed from the decay of naturally radioactive substances in the earth's crust.
What are facts about protactinium?
it's radioactive, and is one of the rarest and most expensive naturally occurring elements. It costs 280$ per gram. It is of the actinide series; which means "radioactive rare earth", so it's related to other really cool elements like plutonium.
What decay causes geothermal energy?
Naturally occurring radioactive decay deep inside the Earth creates geothermal energy.
Is geothermal a renewable fuel?
Geothermal energy is renewable until radioactive decay stops occurring in the Earth's mantle, which won't happen for a long time yet.
What is an sythetic element?
Synthetic elements are those elements that are not naturally occurring on earth, but rather have been synthesized in a nuclear reactor. They are often radioactive with short halflifes.
What formula describes how naturally occurring chemical elements such as uranium thorium and potassium helped to heat the Earth's interior?
During radioactive decays heat is released.
What is the rarest element on earth?
In the earth Astatine is rarest naturally occurring element, less than 30 grams for entire crust.
Where does the heat in the center of the earth come from?
The heat at the centre of the earth is thought to be caused by the decay of radioactive materials, such as uranium, thorium and possibly an isotope of potassium. However this is currently not confirmed.
Which alkaline earth metals are radioactive?
Radium is the radioactive metal among alkaline earth metals.
Which formula below describes how naturally occurring chemical elements such as uranium thorium and potassium helped to heat the Earth's interior?
During radioactive decays heat is released and the center of the Earth is melted.
What is unique about the first 92 elements?
90 of them are naturally occurring on earth. The other 2, technetium and promethium, must be manufactured in reactors or accelerators and are very radioactive. Elements beyond bismuth in the periodic table are all radioactive. This leaves a total of 81 natural non radioactive elements. Element 92, the last, is the only one to have a naturally occurring fissile isotope, Uranium-235, that can be used to power reactors or build fission bombs.That probably wasn't the answer you wanted.
Is actinium a family name or rare earth element series?
Actinium (Ac) is a chemical element.Actinoids is the name of the radioactive elements family which contain actinium.
