In Bohr's model of the hydrogen atom,light is emitted whenever an electron:
A) jumps from a lower to an upper energy level or orbit.
B) reverses its direction of motion in its orbit.
C) jumps from an upper to a lower energy level or orbit.
D) spirals into the nucleus.

Question

Quizplus · Accepted Answer

According to Bohr's model, the electron in hydrogen atom can only occupy certain discrete energy levels or orbits. When an electron jumps from a higher energy level to a lower energy level, it emits a photon with a specific energy and frequency, which corresponds to a specific wavelength and color of light. This phenomenon is known as emission spectrum and is the basis for understanding the atomic structure and behavior. Therefore, the correct choice is (C) jumps from an upper to a lower energy level or orbit, as it is the only option that explains the emission of light and the energy changes in the hydrogen atom.
