Introduction
• The d-block of the periodic table contains the
elements of the groups 3-12 in which the d orbitals 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 orbitals 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.
•
The names transition metals and inner transition
metals are often used to refer to the elements of d-and f-blocks respectively.
• The two series of the
inner transition metals, (4f and 5f) are known as lanthanoids and actinoids
respectively.
