Hund's rule is applicable to:
Correct answer: A. Applicable to all
- A. Applicable to all
- B. O
- C. N
- D. Ne
- E. C
Explanation
According to Hund's rule: Each orbital in a sublevel is separately occupied before any orbital is doubly occupied. All of the electrons in separately occupied orbitals have an equivalent spin (to maximize total spin). If we individually write the electronic configurations and distribute the electrons in sub-orbitals of 2p (2px, 2py, 2pz), the electrons would be distributed according to Hund's rule.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
