| D | Cu | IV | 2 |
Choose the correct answer from the options given below:
A-II, B-III, C-I, D-IV
A-I, B-II, C-III, D-IV
A-III, B-I, C-II, D-IV
A-II, B-I, C-III, D-IV
Transition Series Elements:
Sc Ti V Cr Mn Fe Co Ni Cu Zn
Y Zr Nb Mo Tc Ru Rh Pd Ag Cd
La Hf Ta W Re Os Ir Pt Au Hg
In any transition series, as we move from left to right the d-orbitals are progressively filled and their properties vary accordingly.
f-block Elements:
Ce Pr Nd Pm Sm Eu Gd Tb Dy Ho Er Tm Yb Lu
Th Pa U Np Pu Am Cm Bk Cf Es Fm Md No Lr
The above are the two series of f-block elements in which the chemical properties wonβt change much. The 5f-series elements are radioactive in nature and mostly are artificially synthesized in laboratories and thus much is not known about their chemical properties.
