JEE AdvancedPhysicsAtoms and NucleiMCQ+4 / −1

List-I shows various functional dependencies of energy (E)(E)(E) on the atomic number (Z)(Z)(Z). Energies associated with certain phenomena are given in List-II.

Choose the option that describes the correct match between the entries in List-I to those in List-II.

List–I List–II
(P) E∝Z2E \propto Z^2E∝Z2 (1) energy of characteristic x-rays
(Q) E∝(Z−1)2E \propto (Z - 1)^2E∝(Z−1)2 (2) electrostatic part of the nuclear binding energy for stable nuclei with mass numbers in the range 30 to 170
(R) E∝Z(Z−1)E \propto Z(Z - 1)E∝Z(Z−1) (3) energy of continuous x-rays
(S) EEE is practically independent of ZZZ (4) average nuclear binding energy per nucleon for stable nuclei with mass number in the range 30 to 170
(5) energy of radiation due to electronic transitions from hydrogen-like atoms
