When you fill an orbital the electrons must spin in opposite directions. This results in no two electrons having the same quantum number, a result defined as the Pauli Exclusion Principle. You can have 2 electrons in an orbital. Note that 2py 2px and 2pz are three different orbitals.
If two electrons are to occupy the same orbital, they must have opposite spin.
The orbital that allows no more than two electrons is the s orbital. This is a spherical shaped orbital. Elements with valence electrons lying only in the s orbital are metals.
The requirement ("Pauli Exclusion Principle") is that they must be different in at least one of their properties ("quantum numbers").
the Pauli exclusion principle
Hund's rule: "Two electrons cannot share the same set of quantum numbers within the same system." There is room for only two electrons in each spatial orbital (according to Pauli exclusion principle, mentioned in question).
If two electrons are to occupy the same orbital, they must have opposite spin.
The orbital that allows no more than two electrons is the s orbital. This is a spherical shaped orbital. Elements with valence electrons lying only in the s orbital are metals.
This is usually called the "Pauli Exclusion Principle".
This is the Pauli exclusion principle. Wolfgang Pauli was a Jewish physicist, Nobel prize laureate.
The requirement ("Pauli Exclusion Principle") is that they must be different in at least one of their properties ("quantum numbers").

Each orbital contains maximum or 2 electrons. you could be either asking for this OR s orbital contains maximum of 2 electrons (has 1 orbitals) p orbital contains maximum of 6 electrons (has 3 orbitals) d orbital contains maximum of 10 electrons (has 5 orbitals)
An orbital can hold not more than 2 electrons, and if there are two electrons in the orbital, they must have opposite (paired) spins. Therefore, no two electrons in the same atom can have the same set of four quantum numbers. otherwise the Pauli exclusion principle explain that the feature of particles dependent on its nature. for example electrons is fermion thus 2 electrons can accommodate in one level (orbital) but proton is bozone thus 1 proton accommodate in one level.
I believe no scientist said exactly this. It is the (two) electrons in the same orbital that must have opposite spins. And the scientist who said that was Wolfgang Pauli in 1925. (Pauli exclusion principle)
Pauli's Exclusion Pricipal.A single orbital can only hold 2 electrons.Hund's Rule.The most stable arrangement of electrons is that with the maximum number of unpaired electrons,all with the same spin direction.Aufbau Principle.Electrons fill the lowest energy subshell first before moving to the next subshell.
