Shown below are portion of orbital diagrams representing the ground state electronic configuration of certain elements. Which of them obeys the Pauli's exclusion principle and Hund's rules?
Correct answer: D. Both option B and C are correct
- A. Option A
- B. Option B
- C. Option C
- D. Both option B and C are correct
Explanation
Options A and D are incorrect because two electrons with the same spin are not added to the same orbitals.

About Electronic Configuration
Electronic configuration describes how electrons occupy shells, subshells and orbitals around an atom. Questions use the Aufbau principle, Pauli exclusion principle and Hund's rule to write configurations, identify valence electrons, form ions and explain periodic trends, including common exceptions such as chromium and copper.
