The d-and f-Block Elements
-
The d-block elements are known as transition metals.
-
The f-block elements are known as inner transition metals.
-
4f – metals → lanthanoids
-
5f – metals → actinoids
Electronic Configuration
-
General outer electronic configuration is (n −1)d1−10 ns1−2.
Zn, Cd, and Hg are not regarded as transition elements.
Reason − The orbitals of these elements are completely-filled. [Electronic configuration is (n − 1) d10 ns2]
The d-block elements (transition metals):
-
The d-block elements (group 3 – 12) occupy the large, middle section of the periodic table.
-
In general, t…
