Chapter 4.7, Problem 4.50QAP

Interpretation Introduction

Interpretation: The terms orbital diagram and electron configuration.

Concept Introduction:

Rules for Filling Orbitals:

Aufbau Principle states that the lowest energy orbital is filled first. So electrons usually fill the lowest energy level and the simplest orbital shape first.

Pauli Exclusion Principle states that no two electrons can have the same four quantum numbers. This is why each orbital only has two electrons, one spin up and one spin down.

To discuss: The terms orbital diagram and electron configuration.
