AI overview

An ion is an atom or molecule that has gained or lost one or more electrons, giving it an electrical charge. Ions are important because they enable many chemical reactions and are fundamental to how electricity works in batteries, living cells, and countless other processes.

An ion () is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention. The net charge of an ion is not zero because its total number of electrons is unequal to its total number of protons.
