    Two quantum mechanical spin states which have no classical analogue

  • When a particle as an electron exist in a box, three quantum numbers are necessary to describe the spatial distributioni fo electrons in atoms. The describe an electron in an atom completely, a fourth quantum number, m_(s) called the spin quantum number must be specified. This is because every electron has magnetic moment associated with it which is quantized in one of two possible orientations. Electrons having the same spin strongly repel each other and tend to occupy different region of space. This result of a fundamental law of nature is known as Pauli exclusion principle.
