It's comes down to the Chinese Yin and Yang. Everything has an opposite. Is it possible to have black without white? True without false? Up without down? Yes without no? Good without Evil? One cannot exist without the other.
In computer programming, we learn that a variable cannot truly have a Null (Nothing) value. Even when you set a variable to Null, there's still something in there--Null is an impossibility.
So it is impossible to have Nothing, without Everything. The first two elements of the universe were Yin/Yang...Nothing/Everything.
This is very hard to explain. It was nothing. But how did it look like? Nothing, that's obvious. But everything has a colour. It can have no shape, but it must have a colour. People think that, it was transparent, but you MUST look at something, to know that it's transparent. The same with time. How long did the universe last at non-existing before it. There was no time.
The answer to this question depends on which theory you believe.
If you follow the Big Bang theory, immediately after the Big Bang, the only existent element was hydrogen, which nuclear fusion would have transformed into helium. I don't know anything else afterwards that moment, which lasted less that fraction of a millisecond after the B.B.
If you follow the intelligent design theory, all existing elements were present since the primary tenet of this theory is that the universe was created by an omnipotent, omniscient God.
Variations of both of these theories exist and usually fall somewhere between the two.
Hydrogen was the only element created by the big bang.
However, it was so hot in the early period, that nuclear fusion could occur and helium was produced - along with a few other minor elements - lithium is one. This happened in the first three seconds.
After that - the Universe had expanded and cooled sufficiently that fusion could no longer be sustained.
According to today's best understanding of the conditions at the moment of the
big bang and for some time after it, there were no elements, no atoms, and no
particles from which atoms could form.
The Big Bang did not create any elements. It took almost two billion years for the universe to cool down enough so the first two elements were created. For your purpose, the best answer is hydrogen and helium.
Hydrogen and helium, the two most common elements.
Some scientists theorize that trace amounts of lithium, the next heaviest element, may also have been formed in the immediate aftermath of the Big Bang.
According to most models of the Big Bang, the very early universe was a hot, dense, quark-gluon plasma; elements didn't form until it had expanded and cooled. The first nuclei formed were hydrogen, followed by deuterium (an isotope of hydrogen) and helium; these later captured electrons to form atoms.
The three elements that composed much the early universe were deuterium, helium and lithium. It is surmised that the fact that these are lighter elements accounted for their abundance.
The universe was very chaotic, very much like today. It was composed of mostly gasses and residue left over from the explosion.
Hydrogen and helium are the two most abundant elements in the universe.
Metals nonmetals and metalliods
the atom
Hydrogen and Helium. Also comprised of a core of much heavier elements, all the elements in the universe heavier than hydrogen probably came from supernovae.
Hydrogen and helium make up nearly 100 percent of the matter of the universe. Hydrogen comprises about 75 percent and helium makes up about 25 percent.
They are called bridge elements because the 'bridge' the first two elements with only one electron shell to the rest of the Periodic Table, which have ascending amounts of electron shells. The first two are also the most abundant elements in the universe.
Scientist believe that stellar evolution contained only hydrogen and then helium.
Hydrogen and helium.
The two most common elements in the Universe, and in most stars are - in that order - hydrogen and helium (elements #1 and #2).
Hydrogen, followed by helium.
Hydrogen and Helium. :)
Hydrogen and Helium are the two most common elements in the universe.
Hydrogen and helium are the two most abundant elements in the universe.
Zygote, Universe, and Yttrium
Mainly hydrogen and helium. The reason for this is simply that these are the most common elements in the Universe.
Hydrogen and helium - but especially hydrogen.
There are two elements in the first period, hydrogen and helium.
