Anion (2027)

: When an atom gains an electron, it becomes an anion.

Anions exist in various forms, from simple atoms to complex molecular groups: Cation vs Anion: Definitions & Periodic Table Guide : When an atom gains an electron, it becomes an anion

: The number of electrons gained is indicated by a superscript after the chemical symbol (e.g., Cl−cap C l raised to the negative power for a gain of one electron, O2−cap O raised to the 2 minus power for a gain of two). This surplus of electrons relative to protons gives

An is a negatively charged ion formed when an atom or molecule gains one or more electrons. This surplus of electrons relative to protons gives the particle a net negative charge, a fundamental concept in chemistry that governs how matter bonds and reacts.
