More energy is required to remove an electron from _.
Correct answer: D. Bought Options A and B are correct
- A. Half filled subshell
- B. Completely filled subshell
- C. Partially filled subshell
- D. Bought Options A and B are correct
Explanation
As per Hund's rule, atoms with half-filled or completely-filled orbitals are comparably more stable, so removing an electron from such atoms requires more energy.The orbitals in which the sub-shell is exactly half-filled or completely filled are more stable because of the symmetrical distribution of electrons.

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.
