The energy emitted when an electron moves from a higher energy state to a lower energy state in any atom can be observed as electromagnetic radiation. (a) Which involves the emission of less energy in the $\mathrm{H}$ atom, an electron moving from $n=4$ to $n=2$ or an electron moving from $n=3$ to $n=2 ?$ (b) Which involves the emission of more energy in the $\mathrm{H}$ atom, an electron moving from $n=4$ to $n=1$ or an electron moving from $n=5$ to $n=2 ?$ Explain fully.

Key Concepts

Quantum Energy Levels

Quantum energy levels refer to the discrete, quantized states that electrons can occupy in an atom. Each level is associated with a specific energy value, and electrons can only exist in these allowed states rather than a continuous range of energies.

Photon Emission from Electron Transitions

When an electron transitions from a higher energy level to a lower energy level, the energy difference between these levels is released in the form of a photon, with the photon's energy directly corresponding to the energy gap between the two states.

Discrete Nature of Atomic Spectra

The fact that electrons can only occupy specific energy levels means that the electromagnetic radiation emitted or absorbed during transitions occurs at discrete wavelengths. This leads to the characteristic line spectra observed for elements, as each transition has a specific energy difference.

Bohr Model of the Hydrogen Atom

The Bohr model provides a framework for understanding the quantized energy levels in the hydrogen atom, using the formula E? = -13.6 eV/n². This model explains how the energy difference between any two levels dictates the energy of the emitted or absorbed photon during an electron's transition.
