The quantum numbers can be defined as the number by which size of energy level, shape of energy level, region of maximum probability of finding electrons and spin of electrons can be understood. There are four quantum numbers used to describe the exact position and nature of an electron. They are,

  1. Principle quantum number (n)
  2. Subsidiary quantum number (t)
  3. Magnetic quantum number (m)
  4. Spin quantum number (s)
