The total wave function Psi may be symmetric (denoted by subscript S) or anti symmetric (denoted by the subscript A) depending on the symmtry of the function Psi and S. The function Psi = Psi_(S)S_(S) and Psi_(S) = Psi_(A)S_(A) are obviously symmetric whereas the function Psi_(A) = Psi_(A)S_(A) and Psi_(A) = Psi_(A)S_(S) are antisymmtric. All the functions Psi_(S) and Psi_(A) however do not corresponds to the state of an atom are governed by the Pauli principle. Pauli principle is regulated as one of the general principles underlying the modern quantum statistics. Now if two electron are supposed to have identical quantum numbers then transposition of these electrons will yield a state identical with the initial state and consequantly Psi_(12) = Psi_(21) (for symmetric) and Psi_(12) = - Psi_(21) (for antisymmetric). Hence the condition for satisfying only when the function is equal to zero. Which of the following set of quantum number is incorrect ?
