Question

In an atom, an electron jumps from an energy level of n = 5 to an energy level of n = 2. During this process, a photon was emitted by the atom. a photon was absorbed by the atom. a proton was emitted by the atom. a proton was absorbed by the atom. Now, compare the energy either emitted or absorbed by the atom in Scenario 1 to the energy emitted or absorbed in Scenario 2. An electron jumps from an energy level of n = 5 to an energy level of n = 1. For which scenario is more energy emitted/absorbed? Scenario 1 The energy is the same. It is impossible to tell. Scenario 2

Answer 1

(a) when an e^- jumps from higher energy level to lower energy level energy is emitted. Which means a photon is emitted by atom so option (1) is correct (b) we know, delta E = -z^2 R_H [1/n_f^2 - 1/n_i^2] case I: When n_i = 5, & n_f = 2 therefore delta E = 1/4 - 1/25 = -21/100 z^2 R_H case II: when n_i = 5 & n_f = 1 therefore delta E = 1 - 1/25 = -24/25 z^2R_H so more energy is emitted when e^- jumps from n = 5 to n = 1
