Question

Actinides are f-block elements but 103 element doesnot belong to f-block why?

Answer 1

Bro

The f block elements are the lanthanides and actinides and are called the inner transition elements because of their placement in the periodic table due to their electron configurations. The f orbitals of the electron shell are filled with “n-2.” There is a maximum of fourteen electrons that can occupy the f orbitals.
