Pauli Exclusion Principle

Pauli Exclusion Principle

1. BASIC IDEA: Two electrons in an atom cannot have the same cuantic number.

2. Was formulated in 1925 by Wolfgang Pauli

3. this mean that in one cuantic level, just an electron is allowed.

4. This principle generates the values of spin, wich is 1/2

5. Also, in an orientation, there must be two electrons, except the last level, wich can have one

6. The order of the orientacions must start with the positive spins with a value of +1/2

7. This principle is used in the electronic configurations of the atoms, the spin value is represented with ms, and the three cuantic numbers are l,n and m
