What elements are formed in cool stars?
Elements that are formed in cool stars are heavy but not heavier than iron. (Elements that are heavier than iron are formed in a supernova.)
Compare the elements formed in the big bang with elements formed through nuclear fusion in stars?
No elements were formed in the big bang. After quite some time, hydrogen began to form, and it is the main constituent of stars. The main by-product of nuclear fusion in stars is helium.
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.
All elements in the reriodic table with atomic numbers greathe than of the element are formed by the explosions of collapsing stars?
a. hydrogen :)
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?
When the Universe was created in the moment of the big bang, only simple molecules like helium and hydrogen were formed. These gasses later formed stars which created other elements up to iron, but no heavier.Heavier elements can not be formed by nuclear fusion in stars, and are not believed to be formed during the Big Bag. It is theorized that these elements can only be formed when massive stars explode at the end of their life cycle (in a supernova explosion).Therefore, the presence of gold itself means that a supernova exploded and formed the metals.
Where were all of the other elements formed?
they formed from different types of stars!
What chemical elements are formed inside stars?
All of them except hydrogen.
What elements are formed in cool stars?
Elements that are formed in cool stars are heavy but not heavier than iron. (Elements that are heavier than iron are formed in a supernova.)
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.
How are elements heavier than hydrogen formed?
They are formed inside of stars.
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.
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.
What are the heavier elements in this universe formed by?
a series of stars
Do stars form new elements?
Yes - in fact, most of the elements ONLY exist because they were formed in stars.
