Question

The atomic number of an element is 17, then calculate the total number of electrons present in its s and p orbitals.

Answer 1

1. The element with atomic number 17 is chlorine. 

2. Its electronic configuration is 1s² 2s² 2p⁶ 3s² 3p⁵ . 

3. So, the total number of electrons present in s orbitals = 2 + 2 + 2 = 6. 

4. The total number of electrons present in p orbitals = 6 + 5 = 11.
