Introduction to d-and f-Block Elements:
The d-block of the periodic table contains the elements of the groups 3-12 in which the d orbital are progressively filled in each of the four long periods. The elements constituting the f-block are those in which the 4 f and 5 f orbital are progressively filled in the latter two long periods; these elements are formal members of group 3 from which they have been taken out to form a separate f-block of the periodic table. Transition metals and inner transition metals are often used to refer to the elements of d-and f-blocks respectively.

Points to be remembered for D-block and f-block Elements:
- D-Block elements are collectively known as Transition Elements because properties of these elements vary in between s‐Block and p‐Block elements.
- A transition element should have partially filled (n‐1) d orbital.
- Group 12 elements i.e. Zn, Cd, Hg have completely filled (n‐1) d‐orbital in atomic & ionic state & thus these elements are considered as Typical Transition Elements.
- All these elements are metals and are less electropositive than s‐block elements & more electropositive than p‐block elements.
- Atomic radius decreases from group 3 to 6 because of increase in effective nuclear charge gradually.
- The atomic radii of group 7, 8, 9 & 10 elements (i.e. Fe, Co, Ni) is almost same because pairing of electrons take place in (n‐1)d orbital causing repulsion i.e. shielding of (n‐1)d orbital.
- Group 11 &12 elements i.e. Cu & Zn have bigger size due to strong shielding of completely filled (n‐1)d orbital.
- Transition elements have high enthalpy of atomization/ sublimation Because of large numbers of unpaired electrons in their atoms, they have stronger inter atomic interaction and hence strong metallic bonding is present between atoms.
- Most of transition elements are paramagnetic due to presence of unpaired electrons in (n‐1) d orbital. Image for the d-and f-Block Elements.
