Dianion
text:
A dianion is an anion with a net charge of −2. While there exist many stable molecular dianions, such as BeF4
2− and MgF4
2−, thus far no stable atomic dianion has been found: Electron shielding and other quantum mechanical effects tend to make the addition of another electron to an atomic anion unstable. The most heavily studied atomic dianion is H2−, usually as a short-lived resonance between an electron and a hydrogen ion. In 1976, its half-life was experimentally measured to be 23 ± 4 nanose
