Ion

Definition

An ion is an atom or molecule that has a net electric charge due to the loss or gain of one or more electrons. This charge can be positive, known as a cation, or negative, known as an anion. Ions play a critical role in various processes, including chemical reactions and the operation of particle accelerators.
