Mark me as a brainliest.
Answer:
I hope it's helpfull
Explanation:
☆ Example :
We can take a neutral helium atom as a common Pauli Exclusion Principle example. The atom has 2 bound electrons and they occupy the outermost shell with opposite spins. ... If we draw a diagram then the subshell of the helium atom will be represented with 1 “up” electron and 1 “down” electron.
☆ 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
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
