MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

The atomic number of argon (Ar) is 18. The electronic configuration of argon is 1s^ 2 2s^ 2 2p^ 6 3s^ 2 3p^ 6 . 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
