Ne or Xe have a higher boiling point? why?
In general, higher molar masses will produce higher boiling points.
To determine which element, Ne or Xe, has a higher boiling point, we need to compare their physical properties. Specifically, we need to consider the strength of the intermolecular forces between their atoms.
The boiling point of a substance is directly related to the strength of the intermolecular forces. Stronger intermolecular forces require more energy to overcome, resulting in a higher boiling point.
Both Ne (neon) and Xe (xenon) are noble gases and have similar electron configurations. They both consist of a full valence electron shell, which makes them chemically stable. However, there is a difference in the number of electrons between Ne and Xe. Neon has 10 electrons, while xenon has 54 electrons.
The increase in the number of electrons in xenon compared to neon leads to increased Van der Waals forces, which are the primary intermolecular forces between noble gas atoms. Van der Waals forces arise from temporary fluctuations in electron density and result in the weak attraction between atoms or molecules.
Since xenon has more electrons than neon, the Van der Waals forces between xenon atoms are stronger. Consequently, more energy is required to break these intermolecular forces, resulting in a higher boiling point for xenon compared to neon.
Therefore, Xe (xenon) has a higher boiling point than Ne (neon) due to the stronger intermolecular forces resulting from the larger number of electrons.
