From all of the diatomic gasses, Hydrogen (H2) is the gas with the lowest molecular mass and NO dipole moment or polar bond at all.
20.28 K, -252.87 °C, -423.17 °F
Boiling point of Helium (monoatomic) is even lower (4.22 K, −268.93 °C, −452.07 °F); this is because there are no valence electrons moving BETWEEN two nuclei causing some oscilating charge displacement and attraction, as in H2.

∙ 11y agoHydrogen fluoride has a 19.5 degree C boiling point and hydrofluoric acid (hydrogen fluoride dissolved in water) boils at 108 degrees C. Both of those boiling points are fairly high - the boiling point for undissolved HF, which is a gas at room temperature, is very high.

Is the boiling point hydrogen or oxygen colder?
It is simply the water that freexes. Water is not simply a mixture if hydrogen and oxygen. The two elements are bound together to form water molecules. So it must be treated as its own substance. The behavior of water cannot be explained using the behavior of elemental hydrogen or oxygen. Its properties are different from its constituent elements.
Water changes state at?
It changes state at 0 degree(freezing point), which forms ice, and 100 degree(boiling point), where it turns into vapour. Chemists are trying to create 'ultra pure water', which has almost no foreign substance in it exept H2 and o, and it will freeze at 40 degree celcius!
Which element has lowest atomic number and is not found in nature?
Hydrogen has the lowest atomic number, and is not found in nature as individual atoms, but is found in nature as the diatomic molecule, H2.
Is H2 react with O2 in your atmosphere at normal temperature and pressure?
It's technically possible, but very very slow in the absence of a catalyst.
Which has a strong bond H2 or H2 plus?
H2+ has a stronger bond than H2. The addition of a positive charge to the H2 molecule increases the attraction between the two hydrogen atoms, resulting in a stronger bond.
Which has higher boiling point H2 or He or Ne or Xe or CH4 and why?
CH4
Highest boiling point between NH3 HCl H2 and KI?
The highest boiling point beween these compounds: potassium iodide (KI) with 1 330 0C.
What is the melting point and boiling point of hydrogen?
The freezing point (same as melting point) of H2 is 14.01 K (−259.14 °C, −434.45 °F)The boiling point of H2 is 20.28 K (−252.87 °C, −423.17 °F)
What is the melting point and the boiling point of hydrogen in degrees Celsius?
The boiling point of hydrogen is -252.88°C. or -423.18 °F

What happens when you mix liquid hydrogen with liquid oxygen?
You get a mixture of liquid hydrogen and liquid oxygen. If this is done at ordinary atmospheric pressures, the oxygen will probably freeze, since its melting point is above the boiling point of liquid hydrogen. (I'm not sure of the solubility of solid oxygen in liquid hydrogen.)
Which element has lowest atomic number and is not found in nature?
Hydrogen has the lowest atomic number, and is not found in nature as individual atoms, but is found in nature as the diatomic molecule, H2.

Why does H2 molecules exist when He2 does not?
H2 technically does contain molecules. Or at least, molecule. H2 is two hydrogens covalently bonded, so that the lowest energy level is filled. Since H2 has two atoms (hydrogen and hydrogen), it is not an element, because there is more than one atom. H2 is a molecule itself. However, in context of nature, it is rare that you would ever find an H2 molecule on its own unless you were working with one in a laboratory. So, if you were considering the whole of an H2 gas, there would be many molecules of H2. Short answer: H2 is a molecule itself. Many H2 means there are many molecules of H2.
Is hydrogen a compound or a mixture?
Hydrogen can be an atom (H1), a molecule (H2 or normal hydrogen), an isotope such as deuterium or tritium. Ionized Hydrogen is simply a proton.
Which element has lowest destiny?
Hydrogen is the element with the lowest density. With the atomic mass of the H atom being 1, the molecular mass of hydrogen gas, H2 is 2. This molar mass is lower than any other element in the periodic table.
How do you keep atomic hydrogen H1 from recombining into H2 normal hydrogen once split?
It is only possible if you maintain the splitting temperature.
