Section-C: Comprehension Type
A hydrogen like atom of atomic number Z is in exited state of quantum number 2n. It can emit a maximum energy photon of 204 eV. If it makes transition to quantum state n, a photon of energy 408eV is emitted. Ground state energy of hydrogen atom is −13.6eV.
Calculate minimum energy (eV) that can be emitted be this atom during de – excitation.
