NEETChemistryd and f Block Elements

How are elements in the f-block of the periodic table characterized?

Options

  1. AThey are in groups 1-2.
  2. BThey have fully filled f orbitals.
  3. CThey have partially filled f orbitals.
  4. DThey are in groups 13-18.

Correct answer

C. They have partially filled f orbitals.

Step-by-step solution

The f-block consists of elements in which 4f and 5f orbitals are progressively filled, indicating that they have partially filled f orbitals.
