d and f block elements Assignment Help

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:

1. D-Block elements are collectively known as Transition Elements because properties of these elements vary in between sBlock and pBlock elements.
   
   
2. A transition element should have partially filled (n1) d orbital.
   
   
3. Group 12 elements i.e. Zn, Cd, Hg have completely filled (n1) dorbital in atomic & ionic state & thus these elements are considered as Typical Transition Elements.
   
   
4. All these elements are metals and are less electropositive than sblock elements & more electropositive than pblock elements.
   
   
5. Atomic radius decreases from group 3 to 6 because of increase in effective nuclear charge gradually.
   
   
6. 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 (n1)d orbital causing repulsion i.e. shielding of (n1)d orbital.
   
   
7. Group 11 &12 elements i.e. Cu & Zn have bigger size due to strong shielding of completely filled (n1)d orbital.
   
   
8. 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.
   
   
9. Most of transition elements are paramagnetic due to presence of unpaired electrons in (n1) d orbital. Image for the d-and f-Block Elements.
