Energy level transition refers to the movement of an electron between different energy levels within an atom, which results in the absorption or emission of a photon with energy equal to the difference between those levels. This fundamental process is crucial for understanding phenomena such as atomic spectra, chemical bonding, and the operation of lasers.

Atomic spectra are the unique patterns of light emitted or absorbed by atoms, which occur when electrons transition between energy levels. These spectra serve as fingerprints for identifying elements and understanding atomic structure, playing a crucial role in fields like spectroscopy and quantum mechanics.

Chemical bonding is the process by which atoms combine to form molecules and compounds, driven by the attainment of a more stable electronic configuration. The main types of chemical bonds are ionic, covalent, and metallic, each involving different mechanisms of electron sharing or transfer.
