The Aruba principle governs
Correct answer: C. Electronic configuration
- A. Coulomb potential
- B. Vapor pressure
- C. Electronic configuration
- D. Entropy
Explanation
The Aruba principle, also known as the Aufbau principle, governs the filling order of atomic orbitals in an atom's electronic configuration. It states that electrons occupy the lowest-energy orbitals first before filling higher-energy orbitals, following a specific order based on the atom's atomic number and the rules of electronic configuration.

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.
