UV Spectroscopy
A type of spectroscopy that measures the absorption of ultraviolet light by a chemical substance to determine its characteristics or concentration.
Electron
An electron is a subatomic particle with a negative electric charge, which orbits the nucleus of an atom and is essential in electricity, magnetism, and chemical bonding.
