Two H atoms in th

Answer :

As we know, Energy in the ground state (n=1) is E where Z is atomic number so for energy of two H-atoms in the ground state, whose atomic number is Z=1, the energy will be twice , i.e..

After the inelastic collision between two H-atoms, one of the H-atom should go into first excited state (n=2) so that maximum amount of combined kinetic energy can be reduced. In other words the total energy of two H-atoms after inelastic collision will be


E=Ground state energy + Excited state energy


E [ for H-atom Z=1]


E [ for 1st excited state n=2]


E


Now loss in K.E due to inelastic collision will be the maximum amount of combined kinetic energy reduced


i.e.


Therefore option (a) is correct.
