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.
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.
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.
It's technically possible, but very very slow in the absence of a catalyst.
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.
The product of H2 is hydrogen gas (H2) composed of diatomic molecules.
KI has the highest boiling point among the given compounds because it has stronger intermolecular forces due to its larger size and increased polarizability compared to NH3, HCl, and H2.
The melting point of hydrogen is -259.14Β°C, while its boiling point is -252.87Β°C.
The boiling point of hydrogen is -252.88°C. or -423.18 °F
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.

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.
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.
It's technically possible, but very very slow in the absence of a catalyst.
It is only possible if you maintain the splitting temperature.
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.
The product of H2 is hydrogen gas (H2) composed of diatomic molecules.
