ENERGY LEVEL Meaning and
Definition
-
Energy level refers to the quantized amount of energy possessed by an atom, molecule, or subatomic particle. It is a measure of the state or level of activity of a system at the microscopic level. In physics, energy level is associated primarily with the behavior of electrons in an atom or molecule.
In quantum mechanics, electrons are confined within certain energy levels or orbitals around an atomic nucleus. These energy levels are discrete and are represented by specific quantum numbers. Each energy level is associated with a particular amount of energy and has a unique set of quantum states available to electrons. As an electron moves between different energy levels, it undergoes a change in its energy state, resulting in the emission or absorption of a photon of electromagnetic radiation.
Energy levels are fundamental in understanding the behavior of particles in various physical and chemical processes. For example, the arrangement of electrons in different energy levels determines the chemical reactivity and bonding properties of atoms. Additionally, energy levels are crucial in explaining phenomena such as electronic transitions, luminescence, and the absorption and emission of light.
In summary, energy levels provide a framework for understanding how energy is distributed and exchanged within atoms and molecules, playing a key role in the study of quantum mechanics and providing insights into a range of physical, chemical, and biological processes.

Etymology of ENERGY LEVEL
The term "energy level" originates from the field of physics and has its etymology deeply rooted in the scientific understanding of energy. The word "energy" traces back to the Greek word "energeia", meaning "activity" or "operation". It entered the English language in the early 17th century, and its scientific usage began during the 19th century.
In the early 20th century, with the development of quantum mechanics, the concept of energy levels emerged. The "energy level" refers to the specific quantized amount of energy that an electron can possess in an atom or a molecule. These discrete energy states were discovered and explained by scientists like Max Planck and Niels Bohr.
The term "energy level" itself is an amalgamation of the word "energy" and the word "level", which in this context, signifies a distinct position or state.
