the third quantum number, m, indicates what property of the electron?

The third quantum number, m, refers to the magnetic quantum number. It indicates the orientation or direction of the electron's orbital in three-dimensional space. Specifically, it determines the number of allowed orbitals in a given shell and the specific orientation of those orbitals.

To find out more about the properties of the electron and its quantum numbers, you can consult reliable physics textbooks or educational websites. Specifically, you can search for topics such as "electron quantum numbers" or "magnetic quantum number." These resources will provide detailed explanations and examples to help deepen your understanding.
