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.
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.
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.
When The heavier elements in the universe where formed by?
The heavier elements in the universe were primarily formed through processes such as stellar nucleosynthesis and supernova explosions. In stars, nuclear fusion combines lighter elements like hydrogen and helium into heavier elements up to iron. Elements heavier than iron are typically formed during supernovae, where the intense energy and neutron capture processes create these elements. Additionally, some heavy elements may also form through the merging of neutron stars.
Where did Fred Hoyle believe elements were created?
Fred Hoyle believed that elements were created in the cores of stars through nuclear fusion processes. He coined the term "stellar nucleosynthesis" to describe how heavier elements are formed from the fusion of lighter elements in the intense heat and pressure within stars.
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 the elements formed in earth?
They're not formed here. They were formed in stars - mainly as they exploded.
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.
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.
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.
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.
How were elements heavier than hydrogen formed?
Heavier elements like carbon, oxygen, and iron were formed in the cores of stars through nuclear fusion processes. When massive stars exhaust their fuel, they go supernova, releasing heavy elements into space. These elements then become part of new stars and planets, including Earth.
Where did most of the elements heavier than Hydrogen and Helium form in the Universe?
Elements heavier than hydrogen and helium primarily formed in the cores of stars through nuclear fusion processes. Elements up to iron are formed in the cores of stars, while elements heavier than iron are typically produced in supernova explosions or neutron star mergers. These heavy elements are dispersed into space during these catastrophic events, enriching the interstellar medium from which new stars and planets can form.
The heavier elements in the universe were formed by .?
They were formed in supernovae.
When was selenium made?
Like most elements, selenium was formed in the cores of stars.
