Lesson: Electronic Configurations Chemistry • Second Year of Secondary School

Join Nagwa Classes

Attend live Chemistry sessions on Nagwa Classes to learn more about this topic from an expert teacher!

In this lesson, we will learn how to use electron shell notation to identify elements and describe the electronic configurations of atoms and ions.

Students will be able to

link ideas of electron shells to electronic configuration,
describe the number and composition of electronic orbitals within the principle quantum numbers,
describe the relative energy levels and composition of the principal quantum numbers and orbitals,
use the rules governing the order in which electrons fill and are lost from orbitals.
