Chapter 5, Problem 83A

Interpretation Introduction

(a)

Interpretation:

The electron configuration and orbital notation for atoms of Oxygen needs to be determined.

Concept introduction:

• Aufbau Principle  states that in the ground state electrons of an atom fill the orbital with lowest energy first and upcoming electrons are filled in the order of increasing their energies.
• Hund's rule states that pairing of electrons do not occurs until each and every orbital in a subshell is singly filled with electrons having same spin.
• Pauli Exclusion Principle  states that in an atom no two electrons present in a same orbital having same spin.

Answer to Problem 83A

Electron Configuration of Oxygen $1s^2,2s^2,2p^4$

Orbital notation

Explanation of Solution

Given: Oxygen atom

An orbital diagram refers as the arrangement of the electrons in an atom. In the orbital  diagram, the each  orbitals are shown as squares and orbitals in a sublevel are represented next to each other in a horizontal way.
