Question

Noble gases have very low melting and boiling points. Why?

Answer 1

Noble gases being monoatomic have no Interatomic forces except weak dispersion forces and therefore, they are liquefied at very low temp.

Hence, they have lie boiling points.

Answer 2

Noble gases have very low melting and boiling points because of the weak interatomic interaction.

Noble gases have low melting and boiling temperatures for what reason?

• In general, noble gases have weak interatomic forces since they don't need to establish bonds with one another to achieve a stable configuration. As a result, they have very low melting and boiling temperatures in comparison to other groupings of elements.
• Because Vanderwaals forces grow with size, the boiling point (BP) of elements rises.
• These atoms are stable.
• They rarely form compounds with other atoms because they have fuller outer energy levels.
• As a result of the weak forces of attraction between the atoms being easily overcome, they have low melting and boiling points.
