 Lanthanides and actinides are called inner transition elements because they are a group of elements that are shown as the bottom two rows of the periodic table. ... Lanthanides and actinides belong to the f-block elements, which means that they have filled up their f-orbitals with electrons.

Explanation:
The inner transition elements are the elements that belong to the f-block of the modern periodic table. These elements are also known as the "lanthanides" and "actinides". The added electrons in these elements go to the (n-2)f-orbitals.

Reasons:
• The electronic configuration of the inner transition elements is such that the last electron enters the (n-2)f orbital.
• The (n-2)f orbitals are shielded from the outer world by the (n-1)d and ns orbitals.
• Therefore, the added electrons go to the (n-2)f orbitals.

Conclusion:
Thus, we can conclude that the added electrons in the inner transition elements go to the (n-2)f orbitals.
