The requirement ("Pauli Exclusion Principle") is that they must be different in at least one of their properties ("quantum numbers").

When can two electrons occupy the same orbital according to Pauli's exclusion principle?

Two electrons can occupy the same orbital if they have opposite spins. Pauli's exclusion principle states that no two electrons in an atom can have the same set of four quantum numbers, which include spin.


2 electrons can occupy the same orbital only if?

they have opposite spin


As many as four electrons can occupy the same orbitals?

No. Electrons are fermions, meaning they cannot share the same set of four quantum numbers. Usually when we say "orbital" we only mean the first three, so there is room for two electrons in an orbital (corresponding to the two possible ms values).


When can electrons occupy the same orbital?

only if spins are opposite: one up one down.


What is the maximum number of electrons that can occupy one orbital A.?

The maximum number of electrons that can occupy one orbital is two. This is due to the Pauli exclusion principle, which states that no two electrons in an atom can have the same set of quantum numbers. Therefore, one orbital can hold a maximum of two electrons, each with opposite spins.


What is the orbital notation for an orbital containing two electrons?

It depends what type of orbital these two electrons occupy. But there would be one arrow going up and one arrow going down to show two electrons in the same orbital.


May two electrons occupy the same space orbital in an atom?

No, according to the Pauli exclusion principle, no two electrons can have the same set of quantum numbers in an atom. This means that two electrons cannot occupy the same space orbital if they have the same spin.


Can an orbital contain a maximum of 2 electrons?

Yes, an orbital can contain a maximum of 2 electrons. This is due to the Pauli Exclusion Principle, which states that no two electrons in an atom can have the same set of quantum numbers. Therefore, if two electrons occupy the same orbital, they must have opposite spins, allowing the orbital to hold only two electrons at most.


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)


What is the maximum number of electrons that can occupy orbital?

Pauli stated in 1925 that two electrons can occupy the same orbital only if?

All other orbitals at the sub contain at least one electron
