Helium can be found in underground deposits in the earth. Helium can also be found in stars and other planets.
The helium underground - and extracted from natural-gas - is a by-product of the natural radioactive decay of uranium, though is far too stable to be radioactive itself. It also occurs in very small amounts in the atmosphere. Since it is the first element to be formed in stars by nuclear fusion from the primary hydrogen "fuel", it is abundant throughout the Universe.
Helium is most commonly found in the Earth's crust, often in natural gas deposits. It can also be found in the atmosphere in small amounts. Helium is not typically found in significant quantities in the oceans.
Helium is found in the sun or stars. It is also found in the Earth's atmosphere. +++ And underground: a stable product of the natural radioactive decay of uranium, and extracted commercially from natural-gas. That in the atmosphere may well have been released by volcanoes.
Yes, helium is found in small amounts in Earth's crust. It is a relatively rare element and mainly exists as a result of the decay of radioactive elements such as uranium and thorium. Helium is typically extracted from natural gas deposits.
helium is a gas and is found only in the earth's atmosphere
Through the spectrum. Signatures of an element was found that was not known on Earth. Some years later, it was also found on Earth. Hence the name, "helium".Through the spectrum.

Yes; helium appear from radioactive disintegration of uranium or thorium.
