Скачать или смотреть Aufbau's Principle, Hund's Rule & Pauli's Exclusion Principle - Electron Configuration - Chemistry

This chemistry video explains what is the aufbau's principle, hund's rule, and pauli's exclusion principle and how it relates to orbital diagrams, electron configuration, and quantum numbers. The basic idea of aufbau's principle is that you should fill orbitals with arrows starting from the lowest energy level first. Hund's rule states that you should electrons to degenerate orbitals one at a time with parallel spins. Pauli's exclusion principle states that no two electrons can have the same set of 4 quantum numbers.
