Quantum Numbers

Front

What is the principal quantum number (n)?

Back

The principal quantum number (n) indicates the main energy level of an electron in an atom. It can take positive integer values (1, 2, 3, ...).

What does the azimuthal quantum number (l) represent?

Back

The azimuthal quantum number (l) defines the shape of the electron's orbital and can take values from 0 to (n-1).

Front

What is the magnetic quantum number (m_l)?

Back

The magnetic quantum number (m_l) specifies the orientation of the orbital in space and can take integer values from -l to +l.

Front

What is the spin quantum number (m_s)?

Back

The spin quantum number (m_s) describes the intrinsic spin of an electron and can be either +1/2 or -1/2.
