Number of completely filled orbitals in xenon atom ( Xe ) is

Options

  1. A17
  2. B18
  3. C27
  4. D28

Correct answer

C. 27

Step-by-step solution

The electronic configuration of xenon having atomic number 54 is given as: ₅₄ Xe =1 s^2, 2 s^2 2 p^6, 3 s^2 3 p^6 3 d¹⁰, 4 s^2 4 p^6 4 d¹⁰, 5 s^2 5 p^6 Thus, the number of completely filled orbital in xenon atom ( Xe ) is 27.
