f-block elements are called?
Correct answer: A. Inner transition elements
- A. Inner transition elements
- B. Outer transition metals
- C. Both
- D. None
Explanation
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.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
