The atomic radius of Ag is closest to:
Option: 1 Au
Option: 2 Ni
Option: 3 Hg
Option: 4 Cu
Atomic Size/Radii -
Because of the lanthanide contraction, the size of the elements of the 4d series is similar to their corresponding elements of 5d series.
Thus, the atomic radius of Ag is closest to Au.
Therefore, Option(1) is correct.
