d and f-Block Elements

What are transition elements?

Transition Elements

The elements which are present between s and p-block elements in the modern periodic table are called transition elements.Transition elements have partly filled (n-1) d-orbitals.

In transition elements the last electron enters penultimate d orbitals i.e. (n-1)d orbitals and that is why they are called d-block elements.

The general valence shell configurations of transition elements is  (n-1)d1–10.ns0, 1, 2

All the d-block elements are classified into four series viz 3d, 4d, 5d and 6d series corresponding to the filling of 3d, 4d, 5d and 6d orbitals.

All the d-block elements are classified into four series viz 3d, 4d, 5d and 6d series corresponding to the filling of 3d, 4d, 5d and 6d orbitals.

We will gain in depth knowledge of thransition metals under following subtopics:

What are f block elements?

f –block elements are also called inner transition elements. In these the last electron enters penultimate i.e. (n – 2)f f orbital. The differentiating electron in transition elements may enter either 4f or 5f orbitals based upon which they are differentiated into lanthanides and actinides.

f block elements

Lanthanides: In lanthanides the differentiating electron enters 4f orbital. These are cerium to lutetium. The name lanthanides is because they come immediately after lanthanum.

Actinides: In actinides the differentiating electron enters 5f orbitals. These are thorium to lawrencium. These elements come immediately after actinium.

Electronic configuration: General electronic configuration of f – block elements is (n–2)f1–14(n–1)d0–1ns2

  • Lanthanides: [Xe]4f1–145d0–16s2

  • Actinides: [Rn]5f1–146d0–17s2
