How is it that only 1 spin up and 1 spin down electron are allowed in an atom even though there is no measurement to collapse the state function?

Then how does the third electron 'know' that it can't have spin n,l,m.s = 1,0,0,+1/2 (s w.r.t z)? As you just said yourself, this state is unoccupied.tom.stoer said:it is not true that the "first electron has spin +1/2" and the "second one has spin -1/2" w.r.t. to z.

Electron spin is an intrinsic property of an electron that describes its angular momentum and orientation. It is a quantum mechanical property that can have two possible values: spin up and spin down.
The Pauli Exclusion Principle states that no two electrons in the same atom can have the same set of quantum numbers. This includes the electron spin, which means that if one electron has a spin up, the other electron in the same atom must have a spin down.
Electron spin plays a crucial role in determining the electronic structure and chemical properties of atoms and molecules. It helps explain the arrangement of electrons in orbitals and the formation of chemical bonds.
Yes, electron spin can be measured using a technique called electron spin resonance (ESR) spectroscopy. This method uses a magnetic field to interact with the spin of electrons and produce a measurable signal.
Understanding electron spin and the Pauli Exclusion Principle has led to advancements in fields such as materials science, quantum computing, and molecular biology. It also has practical applications in areas such as magnetic resonance imaging (MRI) and nuclear magnetic resonance (NMR) spectroscopy.
