Chromium has a high boiling point as opposed to nonmetals. Metals tend to have high boiling points.


Why does hydrogen fluoride have a higher boiling point than hydrogen chloride?

The small size and high electronegativity of Fluorine is responsible for high polarity in HF molecules this high polarity is responsible for strong hydrogen bonding with in HF molecules so high amount of heat is required to convert the liquid HF into gaseous state and hence it has high boiling point as compare to HCl.Polar.

Boiling point is a property not a force; but a high boiling point indicate a strong intermolecular force.


Why does H2 have the lowest normal boiling point?

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.
