Quantum Numbers

The location of an electron in an atom can be described by a set of quantum number. It is based equation set by Schrodinger.

Quantum Numbers

• Principal quantum number

• Angular momentum quantum number

• Magnetic quantum number

• Electron spin quantum number

Reminder:

Detailed discussion will be tomorrow (Nov. 17). There will be set of activities for futher understanding of the lesson.
