What temperature did the Universe have when hydrogen and helium formed?
Helium is formed by the fusion of hydrogen at temperatures above 3.106 kelvin.
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.
How are elements beyond hydrogen and helium formed?

Where are gases like hydrogen and helium most abundant?
Hydrogen and helium are the first elements produced in the universe after the big-bang.
What makes up two sun?
Hydrogen is the most common element in the universe as a whole; about 75% of the universe by mass is hydrogen (since hydrogen is also the lightest element, that means that the percentage by number of atoms is even higher) . Helium is second; oxygen is a fairly distant third.
Where did most of the elements heavier than Hydrogen and Helium form in the Universe?
Other elements were formed in stars by nucleosynthesis.
The two elements most abundant in the universe are?
Hydrogen and helium are the two most abundant elements in the universe.
What temperature did the Universe have when hydrogen and helium formed?
Helium is formed by the fusion of hydrogen at temperatures above 3.106 kelvin.
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.
Gas giants have atmospheres composed primarily of helium and what?
Hydrogen and helium, the most common elements in the Universe.Hydrogen and helium, the most common elements in the Universe.Hydrogen and helium, the most common elements in the Universe.Hydrogen and helium, the most common elements in the Universe.
What planet could hydrogen be from?
Hydrogen is not from any planet. Hydrogen was formed in the earliest times of the universe. It is primordial. 78% of ordinary matter in the universe is Hydrogen with most of the rest being Helium. As time went on clouds of hyrdrogen collapsed and formed stars. In the centre of these stars the hydrogen and helium were converted to other elements like silicon and oxygen and iron. It is from these elements that planets were formed later. So far from hydrogen being from a planet, planets are made from hydrogen.
Is it true that Hydrogen and Helium were formed by nuclear reaction in the stars and other elements were formed after the Big Bang?

What are the two most common elements of the universe?
Hydrogen and helium.
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).
How are elements beyond hydrogen and helium formed?

What are the four main physical elements of the universe?
Hydrogen, helium, oxygen, and carbon are the most abundant elements in the universe.
Where are gases like hydrogen and helium most abundant?
Hydrogen and helium are the first elements produced in the universe after the big-bang.
