Helium is formed in the universe through nuclear fusion processes that occur in stars. During the fusion of hydrogen atoms in the core of a star, helium is produced as a byproduct. This process releases a large amount of energy and is responsible for the creation of helium in the universe.
What else can I help you with?
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 common is helium is in nature?
Helium is the second most abundant element in the universe, but it is relatively rare on Earth. It is mainly produced by the natural radioactive decay of heavy elements like uranium and thorium in rocks, and it is often found in natural gas deposits.
How do you think the helium formed in this particular environment?
The helium in this environment likely formed through the radioactive decay of elements like uranium and thorium in rocks deep underground. As these elements decay, they release helium gas as a byproduct, which can then migrate upwards and accumulate in reservoirs beneath the Earth's surface.
Where did most of the elements heavier than Hydrogen and Helium form in the Universe?
Elements heavier than hydrogen and helium primarily formed in the cores of stars through nuclear fusion processes. Elements up to iron are formed in the cores of stars, while elements heavier than iron are typically produced in supernova explosions or neutron star mergers. These heavy elements are dispersed into space during these catastrophic events, enriching the interstellar medium from which new stars and planets can form.
When was first element created?
The first elements were created shortly after the Big Bang, around 13.8 billion years ago. Hydrogen and helium were among the first elements formed in the early universe through nucleosynthesis.
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.
What temperature did the Universe have when hydrogen and helium formed?
When hydrogen and helium atoms first formed in the universe, the temperature ranged from about 3000 to 4000 Kelvin. This temperature allowed protons and electrons to combine to form neutral hydrogen atoms, a process known as recombination. Subsequently, the universe became transparent to radiation for the first time.
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.
How much of the universe ordinary matter is thought to be helium and does the big bang theory support this answer?
Around 24% of the ordinary matter in the universe is thought to be helium. The Big Bang theory supports this by explaining how helium was formed in the early universe through nuclear fusion reactions when temperatures were high enough to convert hydrogen into helium.
What is the name formula and uses for another compound containing helium?
One compound containing helium is helium hydride (HeH+). It is the first compound to be formed in the universe and is found in planetary atmospheres. It is important in astrochemistry for understanding the chemistry of the early universe.
Why is helium common?
Helium is the 2nd lightest element and is the 2nd most abundant in the Universe. Most helium was formed during the Big Bang (See Link), but new helium is being created as a result of the nuclear fusion of hydrogen in stars.
The heavier elements in the universe were formed by .?
They were formed in supernovae.
Helium supported the big bang theory because?
The proportions at which elements occur in the observable universe closely match predictions of the Big Bang theory. According to this model, only the simplest elements would have condensed from the primordial quark-gluon plasma: hydrogen and helium. Heaver elements would have formed inside the first stars and supernovae. Most of the visible matter in the universe would therefore be hydrogen and helium, with heavier elements in lesser numbers, proportional to their atomic weight.
What is the early history of the universe from the viewpoint of a physicist from the birth of elementary particles to the emergence of chemical elements?
Once the Universe got cold enough, atoms could form. It is believed that in the Big Bang, only hydrogen, helium, and small amounts of lithium formed; all heavier elements were formed later, through fusion in stars.Once the Universe got cold enough, atoms could form.

Why do all stars have hydrogen and helium?
Hydrogen and helium were the first elements formed after the Big Bang, and they continue to be the most common elements in the universe due to their abundance. Stars form from clouds of gas and dust in space, and since hydrogen and helium are the most abundant elements available, they make up the majority of a star's composition.
Where does Helium from in the early Universe come from?
Helium is formed by nuclear fusion reactions between hydrogen atoms under extreme temperature and pressures. These reactions still take place today in the centers of stars; in fact, the enormous energy released by such reactions is what drives our own sun.
What is helium made from?
Helium is an element on the periodic table and is one of the basic building blocks of the universe. It is formed through nuclear fusion in stars, releasing helium during the process. On Earth, helium is extracted from natural gas deposits through a process called fractional distillation.
