Why is it likely that life did not form during the very early history of the universe?
In the early Universe, there were no heavy elements around - all the matter of the Universe was in the form of hydrogen, helium, and small amounts of lithium; until the first stars formed, created these heavier elements, and put them out into space when they exploded as supernovae.
What planets contain the fewest heavy elements?
The planet Jupiter has the fewest heavy elements on it (it's all gas). Earth is another planet that has fewer heavy elements.
Where did elements on the periodic table come from?
All the elements on the periodic table are created by stars in our universe. Stars recycle these elements to make new stars and they make new elements. Without stars, there would be no periodic table of elements.
Is all matter in the universe made up of elements?
All visible matter in the universe is believed to be made up of elements, but the nature of "dark matter" is unknown.
Where do the elements of the universe come from?
The Big Bang created over 99.9% of the atoms in the current universe, but these are limited to Hydrogen and a little bit of Helium.Stellar fusion created most of the Helium and the elements from Lithium through Nickel and Iron.Supernova explosions created all the rest of the elements, including quite a few transuranic elements.
What are the most flammable elements?
Hydrogen is the most flammable out of all in the universe
Does the periodic table list all elements in the universe?
The Periodic Table lists all the KNOWN Elementsin the Universe.(We don't know it all, as yet.)
What would the chemical composition of the Universe be like if the only nuclear reactions that had ever occurred in stars had been those involved in energy production?
All elements heavier than iron are made by nuclear reactions that consume energy rather than producing it, so the universe that you describe would have no heavy elements.
Where does the original silicon substance come from?
Silicon, like all elements except hydrogen, was created in stars and eventually distributed through the universe when the star exploded.
What is the relationship between the heavy elements you find on the Earth today and supernovae?
According to the current theories of the origin of the universe, pretty much all matter at the birth of the universe was in the form of hydrogen. The hydrogen then coalesced into stars where the Hydrogen was fused into heavier atoms. The heavy atoms accumulated in the core of the early stars until they went nova and spewed all that stuff out into interstellar space. After lots of time, new star systems developed, and some of the matter in them consisted of those heavy elements from earlier supernovas. Basically, all elements heavier than hydrogen were belched out by long-gone stars. You are composed of stardust.
Are there other elements found in stars than hydrogen and helium?
Yes. All naturally occurring elements in the universe can be found in most stars, though generally only in small concentrations. Massive stars that have depleted the hydrogen in their cores may start producing elements as heavy as iron.
What is the ratio of sulphur?
The ratio of sulphur to all other elements, in the universe, is 0.
