✓ Answer: A Ca
The greater the electropositive character of a metal, the greater its tendency to lose electrons and react; similarly, the greater the electronegative character of a non-metal, the greater its tendency to gain electrons and react. Calcium belongs to the family of alkaline earth metals. While going down the second group of the modern periodic table reactivity of the alkaline earth metals goes on increasing. Reactivity of elements: Calcium(Ca) > Magnesium(Mg) > Aluminium(Al) > Zinc(Zn) > Iron(Fe) > Tin(Sn) > Lead(Pb) > Copper(Cu) > Mercury(Hg) > Silver(Ag).
