Quantum Numbers

  1. Quantum numbers describe the state and position of an electron in an atom.
  2. There are four quantum numbers:
    • Principal Quantum Number (n): Indicates the main energy level or shell of the electron.
    • Azimuthal Quantum Number (l): Defines the subshell and shape of the orbital (0 for s, 1 for p, 2 for d, 3 for f).
    • Magnetic Quantum Number (ml): Specifies the orientation of the orbital in space.
    • S
