• dipole dipole

• H-bond

• London dispersion

• metallic

Which noble gas has the highest boiling point?

• Xe
• Kr
• Ar
• He

NGSS.HS-PS1-1

Why is Xe the noble gas with the highest boiling point?

• All noble gases have only LDF, Xe has the most electrons, making it have stronger LDF forces

• It is the most polar of the noble gases

• Xe has hydrogen bonds

• Xe has more mass so gravity pulls the atoms together

What explains the very high melting and boiling point of water

• Strong dipole-dipole bonds between water molecules
• Strong hydrogen bonds between water molecules
• Dispersion forces which are present in all molecules
• Asymmetrical shape of the polar bonds.
