Answer 2

General electronic configuration of lanthanides and Actinides

General electronic configuration of lanthanides

• Lanthanides are the elements which follow the rule of Afbau's principle due to which they are placed under the F-block of the periodic table.
• The principle states that "the electrons should be filled in the ground state first, next the excited state will be filled."
• Thus the general electronic configuration of lanthanides is identified as $(n-2)f^{1-14} (n-1)s^2p^6d^{0-1}ns^2$.

General electronic configuration of actinides

• In actinides, the electron enters the 5f orbital.
• They are considered as second inner transition element.
• The general electronic configuration is $5f^{1-10}6d^{0-1}7s^2$
