What are the total number of electrons present in s and p orbitals respectively in the argon?

Options

  1. A12 and 6
  2. B8 and 12
  3. C6 and 12
  4. D18 and 6

Correct answer

C. 6 and 12

Step-by-step solution

The atomic number of argon (Ar) is 18 . The electronic configuration of argon is 1s² 2s² 2p⁶ 3s² 3p⁶ . The total number of electrons present in s-orbitals is 2 + 2 + 2 = 6 . The total number of electrons present in p-orbitals is 6 + 6 = 12 . Therefore, the number of electrons in s and p orbitals are 6 and 12 respectively. Answer: 6 and 12
