What has the highest boiling point Kr or Xe or Rn?

Rn (Radon) has the highest boiling point among Kr (Krypton), Xe (Xenon), and Rn. This is because as you move down the noble gas group on the periodic table, the boiling points increase due to the increase in atomic size and London dispersion forces.


What has a higher boiling point Hg NaCl or He?

He, Helium has a boiling point of -269°C (4.2 Kelvins) and it is a noble gas also. Hg, Mercury, is a liquid at room temperature. It boils at +356.73°C (629.88K). NaCl is "table salt", which is a solid. You can liquify salt, and even boil it, at a high enough temperature. Its boiling point is +1,413°C (1,686K). So NaCl has the highest boiling point.


Do Noble gases have a boiling point?

Boiling is the transition of a substance from its liquid phase to a gas. Since a "noble gas" is already a gas it can't boil. Noble gases can be condensed into a liquid phase by subjecting them to the right conditions of temperature and pressure. This liquid can then be turned into its gas phase (aka boiled) by increasing the temperature and/or reducing the pressure.


Why do the noble gases have a lower boiling point?

Due to their electron configuration, the atoms in a noble gas hardly attract each other.

Does gases have a boiling point?

Gas is a phase of a substance. Boiling is the point when a substance chains from liquid to gas. So if it is already gas, it has already reached the boiling point.


What is the state of neon at 20 degrees?

At 20 degrees Celsius, neon is in a gaseous state. Neon is a noble gas with a boiling point of -246 degrees Celsius, so at 20 degrees Celsius, it is well above its boiling point and exists as a gas.
