Among `Cu, Ag, Zn and Cd` which one is the biggest atom? why? 

Text Solution

Verified by Experts

At the end of any series atomic radius increases. Thus in between Cu and Zn, an is bigger atom in between Ag and C, Cd is the bigger atom. In agroup from 3d - element to 4d element atomic radius increases, Thus in between Zn and Cd,Cd is the bigger atom. So among Cu , Ag, Zn and Cd, Cd is the biggest atom.
