What elements are formed in cool stars?
In cool stars, elements such as hydrogen and helium are primarily produced through nuclear fusion in their cores. Elements heavier than helium (e.g., carbon, oxygen, and iron) are formed through nucleosynthesis processes during the later stages of a star's lifecycle, such as in red giant stars or during supernova events.
Is it true that Hydrogen and Helium were formed by nuclear reaction in the stars and other elements were formed after the Big Bang?
Close, but not exactly. Hydrogen is not formed by nuclear reactions in stars, hydrogen was formed not long after the Big Bang, when the expanding universe had cooled sufficiently that an electron and a proton could combine to form a hydrogen atom. Helium and all the other elements that are heavier than hydrogen, were formed by the process of nuclear fusion, in stars.
Compare the elements formed in the big bang with elements formed through nuclear fusion in stars?
Elements formed in the Big Bang are primarily light elements like hydrogen and helium, with trace amounts of lithium and beryllium. Nuclear fusion in stars produces heavier elements through the fusion of lighter elements, such as carbon, oxygen, and iron. This process occurs in the cores of stars through various fusion reactions, leading to the creation of a wide range of elements found in nature.
How is the gold in a wedding ring evidence of ancient stars that ran their life cylcles long before the solar system came into being?
Gold is formed from the fusion of neutron stars, which are remnants of massive stars that have exploded billions of years ago. The elements found in gold, like those produced in neutron star collisions, have to be synthesized through extreme processes beyond what regular stars can create. So, the presence of gold in a wedding ring is a direct link to the cosmic events that occurred long before our solar system's formation.
All elements in the reriodic table with atomic numbers greathe than of the element are formed by the explosions of collapsing stars?
Elements with atomic numbers greater than that of iron (26) are formed through a process called supernova nucleosynthesis, which occurs during the explosive death of massive stars. These elements are created through rapid neutron capture processes, leading to the production of heavy elements like gold, platinum, and uranium.
What is formed from stars?
All elements up to Iron are produced by smaller stars. heavier elements (everything heavier then iron) are produced from larger stars when they go supernova.
Where are heavy elements like nitrogen and iron formed?
Such elements are formed within stars. The heavy elements which are currently here on Earth were formed in stars some time ago, and then they were blown into space in supernova explosions.
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.
How are the elements formed in earth?
They're not formed here. They were formed in stars - mainly as they exploded.
Where were all of the other elements formed?
Most of the other elements were formed in the cores of stars through nuclear fusion processes, while some heavier elements beyond iron are created in supernova explosions. These processes involve the fusion of lighter elements into heavier ones under extreme temperatures and pressures.
Did gold on earth come from a star or was it formed by nature?
Both. Stars are natural. All elements heavier than helium were made in stars.
Do stars form new elements?
Yes - in fact, most of the elements ONLY exist because they were formed in stars.

How are elements formed?
Hydrogen and helium were formed shortly after the creation of the universe (when the protons and alpha particles combined with electrons). Everything else was formed within the core of stars (by fusion reactions).
What are the heavier elements in this universe formed by?
Heavier elements in the universe are primarily formed through nuclear fusion processes within the cores of stars. Elements beyond iron are typically formed in supernova explosions, where the extreme conditions allow for the synthesis of elements such as gold, silver, and uranium.
How are elements heavier than hydrogen formed?
Elements heavier than hydrogen are formed through nuclear fusion processes in stars. When lighter elements fuse together in the intense heat and pressure within a star's core, they can form heavier elements. This process continues throughout a star's life until elements up to iron are created. Elements heavier than iron are formed through supernova explosions or in the collisions of neutron stars.
