Paul Exculsion Principle

Paul Exculsion Principle

1. We can illustrate this by supposing that electrones

2. Two electrons can't have the same 4 quantum numbers

3. How to know if the electrons are in the same orbital?

   • With the table etched in class we need to know n, l, m, and s

4. n, l, and m determine where exactly in which orbital

   • in order to be in the same orbital, two electrons have to have exactly the same values for n, l, and m
     • They share the same orbital within the atom

5. The electron share its territory only if the other electron has a different spin

   • The first electron have "Spin-up" and the second have "Spin-down" so if a third electro try to get in will have trouble with the spin up and spin down so if it want to get in this would be imposible because have to spin in both directions at the same time
     • There is no atomic orbital that can contain more than two electrons so the third electors has to find a new orbital

6. The Pauli Exclusion Principle states that "no two identical fermions may occupy the same quantum state in an atom simultaneously"

   • This means that, no two electrons in an atom can have n, l, ml and ms all the same.
