The quantum numbers of an electron that gives information about its size and shape of energy level, orientation and spin around the nucleus are- (1) Principal Quantum Number, n : The main shell (or level) to which the electron belongs (size). This number has a dependence only on the distance between the electron and the nucleus. The average distance increases with n , and hence quantum states with different principal quantum numbers are said to belong to different shells. (2) Azimuthal (subsidiary) Quantum Number, l : The sub-shell which governs the angular momentum of the electron (shape). In chemistry, this quantum number is very
