Lesson: Quantum Numbers Chemistry

In this lesson, we will learn how to use quantum numbers to describe an electron within an atom.

Lesson Plan

Students will be able to

name the four quantum numbers that describe an electron within an atom,
describe each of the four quantum numbers and its notation,
identify the different values each quantum number can have,
describe the relationship between each of the quantum numbers and atomic orbitals,
write the quantum number for a particular electron within an atom,
determine the total number of electrons that can be assigned to each quantum number (e.g., can have 8 electrons max; , can have 6 electrons max).

Q1:

The quantum numbers for three electrons in an atom of silicon are shown. What is the correct order from lowest to highest energy of these electrons?

Q2:

Which of these sets of four quantum numbers does not exist?

Q3:

If , how many possible values of are there?
