Do Metals Form Cations Or Anions - Web cations are smaller than the parent atom because they've lost electrons. Web metals form positive ions (cations). Anions, on the other hand, gain new ones to become. A magnesium atom must lose two electrons to have the same number. Web even if the the metal has a smaller atomic radius due to occupying less shells, the affinity for the electrons from.
