How would the ionization energy change when the electron in the hydrogen atom is replaced by a particle of mass 200 times that of the electron but having the same charge?

उत्तर
The ionization energy of Hydrogen atom is
EH ∝ me .....(1)
When mass of electron is replaced by a particle having mass=200me, then
EH' ∝ 200me .....(2)
From (1) and (2), we have
EH'=200EH=200×(−13.6)=−2720 eV (∵EH=−13.6 eV)
