Where were the elements that are found in nature formed'?
Hydrogen and helium are thought to be formed during the Big Bang. We also know that helium is formed in stars during the process of stellar evolution. The other elements formed in stars during stellar evolution and end-of-life stellar events (like a supernova). It could be said that with the exception of hydrogen, all the elements formed in stars during one phase or another of the life of stars. This though minute quantities of some isotopes that are found in nature appear in the decay chains of other isotopes and were not themselves created in stars as described.
As heavier elements are formed by fusion a massive star expands into?
Stellar evolution
Where does elements come from?
Chemical elements were formed by stellar nucleosynthesis.
How is raw uranium formed?
As many other chemical elements uranium was formed by stellar nucleosynthesis.
What is a hypothesis to explain the presence of iron and other heavier elements than iron?
Chemical elements are formed in the Universe by stellar nucleosynthesis.
How is uranium formed?
Uranium and the majority of the other elements (excepting H, He, Be, Li, transuranium elements) are formed after the big-bang (creation of the universe) by stellar nucleosynthesis in novas and supernovas.
What is the process that creates uranium?
As many other elements (excepting H, He, Li, Be) uranium is formed by stellar nucleosynthesis.
When did thorium come on this earth?
Thorium is a natural chemical element; chemical elements were formed by stellar nucleosynthesis at the beginning of the universe.
When was phosphorus created?
Phosphorus was discovered in 1669 by a German scientist called Hennig Brand.
When was uranium made?
Uranium and the majority of the other elements (excepting H, He, Be, Li, transuranium elements) are formed after the big-bang (creation of the universe) by stellar nucleosynthesis in novas and supernovas.
Does the interstellar medium have many chemical elements not found in stars?
No all Hydogen and most Helium is from the near beginning. All other elements including more He are formed by stellar processes
What is a stellar nursery?
it is where a star is formed.
