can hydrogen be found in a pure form?

Answer 1

Rarely, it is such a light gas (the lightest) that it rises up and out of the atmosphere.

The heights of Jupiter's and Saturn's atmosphere is mostly hydrogen and other lighter gases.

There is a lot of free hydrogen in the universe, most of the stars are composed of hydrogen and there is a lot of hydrogen gas just floating in interstellar space.

But, of course you are interested in free hydrogen on the planet earth and that is rare. It comes up from the ground in hot vents when heated molecules that have hydrogen in them are broken down and released. Often it is one of the gases that can be found spewing forth from volcanoes, along with gases like hydrogen sulfide.

Most of the hydrogen on the surface of the earth is locked in water, but it exists in a wide range of other compounds, like coal, oil and natural gas. When we burn these hydrocarbons we are burning the hydrogen (hydro) and emitting the carbon into the atmosphere. Then most of that carbon binds with oxygen forming carbon dioxide. When hydrogen is released a lot of it bonds with oxygen and forms water and other compounds, which is why it is so hard to find in its pure form.

According to Wikipedia: http://en.wikipedia.org/wiki/Hydrogen#Natural_occurrence
"Hydrogen is the most abundant element in the universe, making up 75% of normal matter by mass and over 90% by number of atoms. This element is found in great abundance in stars and gas giant planets. Molecular clouds of H2 are associated with star formation. Hydrogen plays a vital role in powering stars through proton-proton reaction nuclear fusion.

Throughout the universe, hydrogen is mostly found in the atomic and plasma states whose properties are quite different from molecular hydrogen. As a plasma, hydrogen's electron and proton are not bound together, resulting in very high electrical conductivity and high emissivity (producing the light from the sun and other stars). The charged particles are highly influenced by magnetic and electric fields. For example, in the solar wind they interact with the Earth's magnetosphere giving rise to Birkeland currents and the aurora. Hydrogen is found in the neutral atomic state in the Interstellar medium. The large amount of neutral hydrogen found in the damped Lyman-alpha systems is thought to dominate the cosmological baryonic density of the Universe up to redshift z=4.

Under ordinary conditions on Earth, elemental hydrogen exists as the diatomic gas, H2 (for data see table). However, hydrogen gas is very rare in the Earth's atmosphere (1 ppm by volume) because of its light weight, which enables it to escape from Earth's gravity more easily than heavier gases. Although H atoms and H2 molecules are abundant in interstellar space, they are difficult to generate, concentrate, and purify on Earth. Still, hydrogen is the third most abundant element on the Earth's surface. Most of the Earth's hydrogen is in the form of chemical compounds such as hydrocarbons and water.[13] Hydrogen gas is produced by some bacteria and algae and is a natural component of flatus. Methane is a hydrogen source of increasing importance."

Answer 2

The first pure element ever discovered was Gold. Gold is called a "nobel" metal because it is nearly inert. Metals like Iron rust, but Gold is resistant to almost all naturally occurring substances. Because of this, it is usually found as a pure metal. The only natural mineral it forms is Gold telluride, an alloy of Gold and the element Tellurium. Atmospheric gasses were the next pure elements discovered, over 10,000 years after Gold was found. The early 19th century was the beginning of modern chemistry and people were coming to realize that substances like Gold were composed entirely of a single material. These substances were called elements. Many experiments then demonstrated gasses like Oxygen and Nitrogen from the atmosphere were also single substances, just as Gold was. By the late 19th century, chemistry had become sophisticated enough to discover tiny traces of other elements present in the atmosphere. Argon is what is called a "noble" gas. In fact it is even more noble than Gold. Argon will not react with anything and thechincally, this element has no chemistry. Then it was discovered there was a whole series of these gasses. They include Helium, Neon, Xenon and a radioactive substance called Radon.

Answer 3

Where Can Hydrogen Be Found

Answer 4

There is a tiny amount of elemental hydrogen in the atmosphere, but on earth most of hydrogen is bonded to many other elements. Any hydrogen gas that enters the atmosphere eventually escapes the earth because of its very low density.

Answer 5

Yes. Some can be found in space.

Answer 6

Yes.

Answer 7

Yes, in the Sun, but leave it there. That's my advice.

Answer 8

off course !
