Helpp plss this is a testt !

The bond energy for the van der waals bond between two helium atoms is 7.9×10−4ev. assuming that the average kinetic energy of a helium atom is (3/2)kbt, at what temperature is the average kinetic energy equal to the bond energy between two helium atoms

May someone me with these science questions

The number of neutrons is equal to the atomic number minus the atomic mass. a. true b. false
