Question

state Pauli 's exclusion principal ..​

Answer 1

Answer:

Pauli's Exclusion Principle states that no two electrons in the same atom can have identical values for all four of their quantum numbers. In other words, (1) no more than two electrons can occupy the same orbital and (2) two electrons in the same orbital must have opposite spins (Figure 46(i) and (ii).

Answer 2

Explanation:

Formula

\psi=\psi_{1}(a) \psi_{2}(b)

\psi = probability amplitude that electron 1 is in state a and electron 2 is in state b

\psi_{1}(a) = probability amplitude that electron 1 is in state a

\psi_{2}(b) = probability amplitude that electron 2 is in state b

The Pauli Exclusion Principle states that, in an atom or molecule, no two electrons can have the same four electronic quantum numbers. As an orbital can contain a maximum of only two electrons, the two electrons must have opposing spins. This means if one is assigned an up-spin ( +1/2), the other must be down-spin (-1/2).
