Lesson: Modern Atomic Theory 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 describe the concepts of modern atomic theory.

Students will be able to

describe the limitations of the Bohr model of the atom,
state the wave–particle duality of the electron,
describe in qualitative terms the Heisenberg uncertainty principle in relation to position and velocity,
describe in qualitative terms the wave mechanical description of an atom,
explain how the location of an electron within a certain volume of an atom is defined by probability.
