A molecule or atom that has fewer electrons than protons and therefore which possesses a positive electrical charge.

Cations form from neutrally charged atoms or molecules either via the gain of positively charged ions such as protons (which are hydrogen ions) or, more commonly, instead via the loss of electrons (which are negatively charged).

See also ionic bond, cathode, or by contrast anion.
