After the big bang (if you believe in the big bang) the universe consisted of many subatomic particles, or parts of an atom. Because of the big bang, they were vey hot. However, once cooled, the particles started to form into hydrogen atoms. (There were a few of helium and lithium mixed in there, too.)
Then, gravity started to form the hydrogen into stars. Stars, believe it or not, are like element factories. Stars produce hydrogen until they can't produce any more. Once this happens, the hydrogen atoms start to fuse together to create helium, until it can't create ay more helium, and so on. This continues all the way up to iron.
Once the star can't make any more iron, it burns out and explodes into a supernova. This releases all of the elements made by the star.
Finally, the explosion can cause some of the newly made elements to fuse into heavier elelments, such as silver and gold.

∙ 14y agoSome (Hydrogen, Helium and a little Lithium) were created in the 'Big Bang' as energy condensed into matter. The rest of the elements are formed out of Hydrogen and Helium in the cores of stars.

∙ 12y agoThe lightest elements (i.e., hydrogen, helium, lithium) were created during the Big Bang. Heavier elements (i.e., oxygen, carbon, silicon) were created by fusion reaction in stars. The most massive stars could create elements as heavy as iron.
The heaviest elements (i.e., uranium) are only created naturally during a supernova.

∙ 12y agoMost elements - almost everything except hydrogen and helium - were formed in stars, and thrown into space in supernova explosions, where they became part of the next generation of star systems.

When was Table of the Elements created?
Table of the Elements was created in 1993.
What are all the elements that do not have isotopes?
There are many elements that have only one naturally occurring isotope. When you get to transuranic elements the elements all have no naturally occurring isotopes. But all elements have isotopes, they just have to be created, maybe in a nuclear reactor or particle accelerator or a supernova explosion.
All of the elements heavier than oxygen are created by fusion reactions in?
black holes
Who was one of the first people to arrange all elements into families?
The Russian chemist Dmitri Mendeleev was the first person to arrange all elements into families. He created the periodic table of elements and wrote a textbook between 1868 and 1870.
What role did supernova play in creating the natural elements?
It is precisely the supernovae that created those elements and dispersed them into space.It is precisely the supernovae that created those elements and dispersed them into space.It is precisely the supernovae that created those elements and dispersed them into space.It is precisely the supernovae that created those elements and dispersed them into space.
What elements are left after a star explodes?
All of them. A star begins to die when it creates Iron. Then it creates all the elements heavier than Iron. It has already created the elements lighter. Thus when the star explodes it spreads the elements it has created witch is all of them.
How many elements have been created or discovered by scientist?
All the elements after Uranium (U).
What is the important of the big bang?
It created the universe, it created all the elements we use and live with.
What do elements 43 61 93-109 have in common?
All of these elements are synthetic. They are not found on Earth in nature, but are all created in nuclear labs.
What is the importance of big bang theory?
It created the universe, it created all the elements we use and live with.
How discovered the element ununbium?
All of the "Unun" elements we're created in particle accelerators by smashing to larger elements together. By doing so, they created new elements like "Unb" that last for only a fraction of a second. In case you were wondering, all the elements with "Ununs" are placeholder names for further names.
When was Reign of Elements created?
Reign of Elements was created in 2002.
When was Elements of Semiology created?
Elements of Semiology was created in 1964.
When was Elements of Dynamic created?
Elements of Dynamic was created in 1887.
When was The Elements - song - created?
The Elements - song - was created in 1959.
When was Raw Elements created?
Raw Elements was created in 2002.
When was The Elements of Style created?
The Elements of Style was created in 1919.
