The squished hydrogen is a precursor to a state of matter first proposed in the 1930s, called atomic solid metallic hydrogen. When cooled to low enough temperatures, hydrogen (which on Earth is usually found as a gas) can become a solid; at high enough pressures, when the element solidifies, it turns into a metal.
Keeping this in view, what is hydrogen as a solid?
Solid hydrogen is the solid state of the element hydrogen, achieved by decreasing the temperature below hydrogen’s melting point of 14.01 K (−259.14 °C; −434.45 °F). Solid hydrogen has a density of 0.086 g/cm3 making it one of the lowest-density solids.
One may also ask, what color is solid hydrogen? At relatively low pressures, the compressed solid hydrogen was transparent. As the compression intensified, it began to turn opaque and black. But at 495 Gpa, the hydrogen was shiny and reflective, indicating its transformation into a metal (although the researchers can’t be sure whether it was solid or liquid).
Thereof, what is the state of hydrogen?
Hydrogen gas has the molecular formula H2. At room temperature and under standard pressure conditions, hydrogen is a gas that is tasteless, odorless and colorless. Hydrogen can exist as a liquid under high pressure and an extremely low temperature of 20.28 kelvin (−252.87°C, −423.17 °F).
Is solid hydrogen a metal?
Hydrogen is one of the best-studied elements in the Universe – and in its natural state, it’s definitely not a metal. It’s not shiny and it doesn’t conduct electricity. But back in 1935, researchers predicted that under certain high-pressure conditions, hydrogen could take on metallic properties.

How do you freeze hydrogen?
The simple answer to your question is: use liquid helium. Hydrogen freezes at about 14 degrees above absolute zero (14 Kelvin), while helium doesn’t even turn to a liquid until 4.2 Kelvin.

Is water flammable?
Water is made up of two elements, hydrogen and oxygen. Hydrogen is flammable, but oxygen is not. You can’t burn pure water, which is why we use it to put out fires instead of starting them. You can, however, break it down into hydrogen and oxygen by putting energy into it, in the form of an electric current.
Is metallic hydrogen stable?
The much more important consideration is that metallic hydrogen may prove to be stable (although its state will, of course, be metastable) even under zero or comparatively low pressure.
Is hydrogen gas poisonous?
Hydrogen isn’t poisonous, but if you should breathe pure hydrogen you could die of asphyxiation simply because you’ll be deprived of oxygen. Worse, you won’t necessarily know that you’re breathing hydrogen because it’s invisible, odorless and flavorless — much like oxygen.
What does hydrogen look like?
In its commonest form, the hydrogen atom is made of one proton, one electron, and no neutrons. Hydrogen is the only element that can exist without neutrons. Hydrogen is a colorless, odorless gas which exists, at standard temperature and pressure, as diatomic molecules, H2.
What is hydrogen made of?
Composed of a single proton and a single electron, hydrogen is the simplest and most abundant element in the universe. It is estimated that 90% of the visible universe is composed of hydrogen. Hydrogen is the raw fuel that most stars ‘burn’ to produce energy.
What is another name of hydrogen?
protium
What is h2 called?
H2 is also called molecular hydrogen.It consists of two protons and two electrons. Consequently it is the most common form of Hydrogen because it is stable with a neutral charge. H2 is not a free radical. It is the antioxidant in ‘hydrogen-rich’ water. H2 is the smallest molecule in the universe.
Where can we find hydrogen?
Hydrogen is easily the most abundant element in the universe. It is found in the sun and most of the stars, and the planet Jupiter is composed mostly of hydrogen. On Earth, hydrogen is found in the greatest quantities as water.
Does hydrogen have a half life?
Hydrogen (1H) has three naturally occurring isotopes, sometimes denoted 1H, 2H, and 3H. The first two of these are stable, while 3H has a half-life of 12.32 years. The ordinary isotope of hydrogen, with no neutrons, is sometimes called protium.
What does hydrogen look like in its normal state?
Hydrogen is the lightest of the elements and is the most abundant element in the universe. At standard temperature and pressure hydrogen is a colorless, odorless, and tasteless gas. Hydrogen is very flammable and burns with an invisible flame. It burns when it comes into contact with oxygen.
Is hydrogen a solid gas or liquid?
Whether hydrogen is a solid, liquid or gas depends on the temperature. It is a gas at most normal temperatures, as it boils at around 10K, which gives it the lowest boiling point of any element except helium.
Is water a compound?
Water Oxidane
Can hydrogen be a liquid?
Liquid hydrogen (LH2 or LH2) is the liquid state of the element hydrogen. Hydrogen is found naturally in the molecular H2 form. To exist as a liquid, H2 must be cooled below its critical point of 33 K. As for any gas, storing it as liquid takes less space than storing it as a gas at normal temperature and pressure.
Is everything made from hydrogen?
No. Everything is not made of hydrogen. But, the elemental mass fraction of H in the universe is 73.9% so most of the atoms in the universe are H. In the early days of the universe, the mass fraction of H would have been substantially higher, but fusion and explosions created larger elements.
Is it possible to freeze hydrogen?
Difficult, but not impossible. There are a couple of ways, in fact. The BP of LH2 is -252.8C and the melting point is -259.14 C, about 6 degrees C lower. If you were to take a container of LH2 and start to pull a vacuum on it, the temperature would fall and eventually it would freeze solid.
Is solid helium possible?
Helium is one of only two natural elements that has never been observed bonding to another element in a compound. At normal atmospheric pressure helium does not solidify. At 25 atmospheres of pressure helium is a solid at 0.95 K. As the pressure rises, the temperature at which solid helium exists also rises.
