JEE MAIN - Chemistry (2020 - 7th January Morning Slot - No. 22)
The atomic radius of Ag is closed to :
Au
Cu
Hg
Ni
Explanation
Atomic radius of Ag and Au is nearly same due
to lanthanide contraction.
In periodic table in group 1, 2, 3 from top to bottom radius increases but from group 4 to 12 size increases for 3d to 4d series elements but size of 4d and 5d series elements are approximately same.
