The observed proportions and distribution of hydrogen and helium are consistent with what would be expected if the Big Bang model were accurate. The Big Bang model describes how, from the cooling universe, the simplest atoms would have condensed from the hot broth of fundamental particles most easily: a proton and an electron, forming hydrogen. Far fewer particles would have combined to form helium, requiring two protons and one or two neutrons. The likelihood of spontaneous condensation of elements then decreases rapidly with the complexity of the element, so very few heavier elements could have formed that way. Initially, almost all of the visible matter in the universe consisted of hydrogen and helium, according to the Big Bang model. Heavier elements would have been formed through nucleosynthesis in the cores of stars and supernovae. When we look at the proportions and distribution of the elements, especially hydrogen and helium, this is indeed what we find.
What else can I help you with?
Where are gases like hydrogen and helium most abundant?
Hydrogen and helium are the first elements produced in the universe after the big-bang.
The hydrogen-to-helium ratio is an important piece of evidence for the big bang What is the minimum hydrogen-to-helium ratio observed?
The minimum hydrogen-to-helium ratio observed is approximately 25% hydrogen to 75% helium. This ratio is consistent with predictions based on the conditions of the early universe during the Big Bang.
How was tin created in the big bang?
It wasn't. Right after the Big Bang, there was only hydrogen (including deuterium), helium, and minute amounts of lithium. Apart from that, all the so-called metals - i.e., elements other than hydrogen or helium - were created in supernovae.
What produced the helium now present in the sun's core?
The big bang produced the helium no present in the sun's core. The universe cooled down enough after the big bang to form the formation of helium and hydrogen.
What is the process called which formed elements from hydrogen and helium after the Big Bang occured?
The process is called nucleosynthesis. After the Big Bang, the nucleosynthesis process involved the fusion of hydrogen and helium nuclei to form elements like lithium, beryllium, and some trace amounts of heavier elements.

Which element was created during the big bang?
Hydrogen and helium were the two main elements created in abundance during the Big Bang nucleosynthesis. These elements were formed in the first few minutes after the Big Bang, when the universe was hot and dense enough to support nuclear fusion.
Is hydrogen found in the universe formed by stars?
No. The hydrogen in the universe was formed during the Big Bang. Stars consume hydrogen, fusing it into helium.
How was tin created in the big bang?

What 2 elements started the big bang and everything in your universe?
No element "started" the big bang. The big band eventually produced mainly hydrogen and helium, which may be the answer you were looking for.
Where were helium and and hydrogen formed?
Hydrogen was initially formed in the 'Big Bang' which initiated this universe. Helium is formed by the fusion of hydrogen atoms, inside stars. This reaction is what causes stars to shine, and give off heat.
What produced the helium now present in the sun's core?
The big bang produced the helium no present in the sun's core. The universe cooled down enough after the big bang to form the formation of helium and hydrogen.
What is helium's origion?
Some was made in the big bang and the rest is made by the process of hydrogen fusion in the cores of stars.
The two elements most abundant in the universe are?
Hydrogen and helium are the two most abundant elements in the universe.
What is the process called which formed elements from hydrogen and helium after the Big Bang occured?
The process is called nucleosynthesis. After the Big Bang, the nucleosynthesis process involved the fusion of hydrogen and helium nuclei to form elements like lithium, beryllium, and some trace amounts of heavier elements.
Modern view of the galaxy formation?
The Big Bang leads to huge clouds of hydrogen and helium, which eventually condense into galaxies.
