MCQ
Differentiating electron in inner transition elements enters the ________ orbital.
- As
- Bp
- Cd
- Df
Explanation:
In inner transition elements, the differentiating electron enters into f orbitals. So these elements are called f-block elements.
The ‘f’ – block elements are also known by the name of inner transition elements. In these elements, the last electron usually enters the penultimate i.e. (n – 2) f of the orbital.
