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.

∙ 10y agosymmetric and asymmetric systems depend on its nature.
Another answer: The basic idea is that no two electrons in an atom can share the same quantum state. There's more to it, but that's a common application.
If you need more technical details:
The Pauli exclusion principle applies to all particles called "fermions", for example electrons.
Fermions have "half integer spin".
The Principle doesn't apply to "bosons" which are particles with "integer spin".
Fermions have antisymmetric "wavefunctions".
(Bosons have symmetric wavefunctions.)
There is a "related link" below. This link is mainly about the Pauli Exclusion Principle as applied to electrons in atoms.

∙ 9y agoThe Pauli exclusion principle says that no two fermions can occupy the same quantum state at a time. Electrons are fermions and the spin is in a quantum state. Two electrons occupy the same orbital only if they have opposite spins.

∙ 12y agoPauli's exclusion principle states that no two electrons have all the 4 quantum numbers same in an atom.Electrons may have same principle or azimuthal or magnetic quantum numbers same.but there will definetely be a change in spin quantum number.hence,no two electrons in an atom have all same 4 quantum numbers.

How can you use exclusion in a sentence?
When referring to tax, an exclusion law is an item that is excluded from the gross income. An example sentence would be: Because of the exclusion laws, our tax refund was bigger.
Why does matter take up space?
Matter takes up space because it exists. It takes up space because it has depth. If it didn't take up space it would be a 2D object and nothing could be made of matter. Because everything is made up of matter, matter must take up space.
How do you explain the world?
Well first.. I would research information about the world. And then I would talk about it. That is how you explain the world.
What is Bonding by electron transfer?
Valence electrons are the parts of the atoms involved It is the electron. As electrons are fermions (1/2 integer spin) they obey the Pauli exclusion principle so that no two electrons can occupy the same energy level. This gives rise to the electrons of different atoms unable to be in the same energy level and this is where the bond comes from. If they could occupy the same energy levels like bosons (eg the photon in laser light) then there would be know chemistry.

Who was Swiss physicist who formulated the Exclusion Principle?
If you are talking about the Pauli Exclusion Principle, then it would be Wolfgang Pauli. However, Pauli is Austrian.
The Pauli exclusion principle states that?
Simple stated, no two electrons can have the same quantum numbers. Electrons at the same level would have a + and - spin.
Is it possible for atoms of different elements to have the same number of electrons?
no it is not possible"Pauli exclusion principle states that no two electronsin an atom can have the same set of four quantum numbers"
Do the electrons within the electron cloud have different amonts of energy?
Of course, if any two were in the same state it would violate both fermi statistics and the pauli exclusion principle.
What must be true about electrons sharing the same atomic orbital?
The Pauli exclusion principle would require that an electron sharing the same orbital would have to have opposite spin from the other particle in the pair. They therefore have different spin quantum numbers of +(1/2) and -(1/2)
Could a nucleus that has more than one proton but no neutrons exist explain?
Such a nucleus would be unstable due to the Pauli Exclusion Principle requiring the protons to have anti-aligned spins and thus a negative binding energy which would force the protons apart. There has been some recent (2008) experimental evidence that suggests a Diproton, or Helium-2 nucleus, may exist for a fraction of a billionth of a second under certain conditions and may have a role to play in the creation of elements inside stars.
The difference between Aufbau principle and pauli exclusion principle?
according to hund's rule ,electrons are distributed among the orbitals having equal energy [degenerate orbitals] in such a way that the number of unpaired electrons is maximum.In other words , if the number of electrons is less or equal to the orbitals of same energy then all these electrons will be unpaired.But when the number of electrons is more than the available orbitals , then first all the orbitals will be singly occupied and then pairing of electrons will start.Due to this interelectronic repulsion will be minimum when the electrons occupy separate orbitals and when number of unpaired electrons with same spin is greater than exchange energy will also be greater this stablizes the system. While pauli's exclusion principle is that an orbital can accomodate not more than 2 electrons that too with opposite spins.
Is it possible for two metals to have the same emission spectrum?
No. It is not possible for two metals to have the same emission spectrum. For metals to have the same emission spectrum, they would need for their electrons to have duplicate orbitals. That would be impossible due to the exclusion principle.
Who hypothesized that only two electrons can occupy an orbital?
The bottom-line answer is because that is how nature works! However, there are somewhat less profound explanations, but they are really just rules which say that this must happen -- and don't ultimately answer "Why?". The Pauli Exclusion Principle says that all electrons in an atom must have four unique quantum numbers -- no two can have all four the same. This rule forbids more than 2 electrons existing in the same orbital because there are two possible quantum numbers available for that orbital -- electron spin of +1/2 and -1/2. But again, this rule just says that there can't be more than 2 electrons per orbital because of the uniqueness of quantum numbers -- but it doesn't say why quantum numbers must be unique! In the end, it really just is the way it because that's the way it is!
What happens when two or more organisms coexist in the same niche?
If two species occupied the same niche, they would be competing for the exact same resources. The competitive exclusion principle states that one of the species would drive the other to extinction.
Why do two electrons in the same orbital have to have opposite spin states?
Yes. Always. Otherwise they would break the fundamental rules of quantum mechanics, which say that no two electrons can have the same four quantum numbers -- and spin is the 4th quantum number. If two e- are in the same orbital, they share 3 quantum numbers, but the spin quantum number must then be different.
