Ionen zijn atomen met extra elektronen of ontbrekende elektronen. Wanneer de buitenste orbitaal van een atoom elektronen wint of verliest (ook bekend als valentie-elektronen), vormt het atoom een ion. Een ion met meer protonen dan elektronen draagt een netto positieve lading en wordt een kation genoemd. earl\\u0027s rib palace bricktown
