Metals can carry a net negative charge in electrides and negatively charged atomic clusters
the verdict
SUPPORTED
the evidence backs this
confidence 80/100
Multiple studies and reviews confirm that electrides are ionic materials featuring interstitial electrons that function as negative anions, and advanced compounds can even host transition metals in exceptionally negative oxidation states.
