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.

H2 has the lowest normal boiling point because it has the weakest intermolecular forces among the hydrogen halides. The boiling point is a measure of the strength of forces holding molecules together, and in the case of H2, the forces are the weakest due to its small molecular size and low molar mass.

Hydrogen 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.

Which has higher boiling point H2 or He or Ne or Xe or CH4 and why?

Xe has the highest boiling point among the options provided because it has the largest atomic size and the greatest London dispersion forces, which are stronger than the weak van der Waals forces present in the other elements.


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.


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 reacts with acid to form H2 a chemical or physical properties?

This is a chemical property, as it involves a chemical reaction where hydrogen gas is produced when the substance reacts with an acid. Physical properties refer to characteristics such as color, state, density, and boiling point.


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.


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.


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.


What is the product of H2?

The product of H2 is hydrogen gas (H2) composed of diatomic molecules.
