The sequence of filling atomic orbitals is govermed by …….. Principle

Explanation

To answer the question regarding the principle that governs the sequence of filling atomic orbitals, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Atomic Orbitals**: Atomic orbitals are regions around the nucleus of an atom where electrons are likely to be found. Each orbital has a specific energy level.

2. **Filling Order of Electrons**: Electrons are added to atomic orbitals in a specific order based on their energy levels. The order in which these orbitals are filled is crucial for determining the electron configuration of an atom.
