The atomic radius of $$Ag$$ is closed to :
A$$Cu$$
B$$Hg$$
C$$Ni$$
D$$Au$$
Correct Answer
Solution
The atomic radius of the second and third transition series are almost the same. This phenomenon is associated with the intersection of the 4f orbitals which must be filled before 5d series of elements begin. The filling of 4f before 5d orbitals results in a regular decrease in radii called Lanthanoid Contraction. The atomic radius of $$ Ag$$ is closest to $$Au$$.
