Question

Review the noble gases in the periodic table. As molar mass increases, the number of electrons increases, resulting in

more dipole-dipole interactions.

greater dispersion forces.<--- My answer, correct?

decreases in the boiling point.

activation of additional attractive forces.

Answer 1

greater dispersion forces is in fact correct

Answer 2

greater dispersion forces.

Step-by-step explanation:

Dispersion forces are also known as London dispersion forces depends on the molar mass of the gas. The higher the molar mass of the molecule the greater is the dispersion forces. London dispersion forces exist between all atoms of the molecule.

Dispersion forces are weak intermolecular forces. They occur when instantaneous dipole moments are created by the electron cloud of an atom.
