d - block and f - block Elements
The atomic radius of $$Ag$$ is closed to :
Give reason for: $$Zr$$ and $$Hf$$ have almost identical radii.
$$Zr$$ and $$Hf$$ have almost identical radii due to filling of 4forbitals which have poor shielding effect (lanthanoid contraction).
The atomic radius of $$Ag$$ is closed to :
Which of the following does not represent the correct order of the property indicated?
Account for: Silver atom has completely filled $$d$$-orbitals ($$4d^{10}$$) in its ground state yet silver is a transition element.
The decreases in atomic volume from Cr to Cu is very negligible because
The atomic radii of the elements are almost same of which series:
