Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Energy Levels in Atoms

In an atom, electrons occupy specific energy levels, denoted by quantum numbers (n). The energy levels are quantized, meaning electrons can only exist at certain distances from the nucleus. The difference in energy between these levels determines whether energy is absorbed or emitted during electron transitions.

Photon Emission and Absorption

When an electron transitions from a higher energy level to a lower one, it emits a photon, releasing energy. Conversely, if an electron moves from a lower to a higher energy level, it absorbs a photon. The energy of the photon corresponds to the difference in energy between the two levels involved in the transition.

Spectral Lines and Wavelength

The light emitted or absorbed during electron transitions results in spectral lines, which are unique to each element. The wavelength of the emitted or absorbed light can be calculated using the Rydberg formula, which relates the wavelengths to the energy levels of the electron transitions. This concept is crucial for understanding atomic spectra and identifying elements.
