According to Niels Bohr,an electron in an excited state could give off
A)at most a single photon until the atom was excited again.
B)several photons in a series of transitions to the ground state.
C)a continuous cascade of photons for a high-level transition.
D)none of these

Question

Quizplus · Accepted Answer

According to Bohr's model of the atom, when an electron is excited to a higher energy level, it can return to its ground state by emitting one or more photons with energies equal to the difference between the two energy levels involved in the transition. Therefore, an electron in an excited state could give off several photons in a series of transitions to the ground state, making choice B the correct answer. Additionally, choice A is incorrect because an excited atom can emit multiple photons, not just one. Choice C is also incorrect, as a high-level transition does not necessarily result in a continuous cascade of photons but can involve several discrete photon emissions.
