Is cadmium an alkaline earth metal
WebThe alkaline earth metals in group 2 are always +2 when they form cations. Aluminum and the elements in group 3 are always +3 when they form cations. Zinc and cadmium always form +2 cations. Although silver can form both +1 and +2 cations, the +2 is so rare that we usually name Ag + as silver ion, not silver (I) ion.
