Can two electrons occupy the same quantum state?

The Pauli Exclusion Principle actually states that two electrons cannot occupy the same quantum state. To occupy the same quantum state, they would have the same n (quantum level), l (subshell), ml (orbital), and ms (spin).

Why can’t two electrons in the same orbital be in the same place or travel bonded together?

This is because of the Pauli exclusion principle, which says that no two electrons in a given atom can have identical quantum numbers. Each electron has 4 quantum numbers, usually indicated N, l, m, and s (or “spin”). An “orbital” is usually defined as an electron path in space, specified by a particular N, l, and m.

Why can’t two electrons have the same spin?

The Pauli Exclusion Principle states that, in an atom or molecule, no two electrons can have the same four electronic quantum numbers. As an orbital can contain a maximum of only two electrons, the two electrons must have opposing spins.

Under what conditions can 2 electrons be in the same orbital?

Pauli’s Exclusion Principle states that no two electrons in the same atom can have identical values for all four of their quantum numbers. In other words, (1) no more than two electrons can occupy the same orbital and (2) two electrons in the same orbital must have opposite spins (Figure 46(i) and (ii)).

Which set of quantum numbers is impossible for an electron?

The answer choice that gives an impossible set of quantum numbers has a negative second quantum number. The first and second quantum numbers will always be greater than or equal to zero.

Why can’t electrons occupy the same quantum state?

Electrons are fermions (non-integer spin) so therefore they behave according to the exclusion principle, which says they can’t occupy the same quantum state at the same time.

Why can’t two particles with the same spin have different quantum states?

It’s an observed fact of nature that two identical Fermions (particles with half-integer spin, which includes electrons having spin 1/2) cannot be in the same quantum state. There is no deeper explanation.

Can an orbital have more than 2 electrons?

[SOLVED] An orbital cannot have more than two electrons and they must have opposite spins. An orbital cannot have more than two electrons and they must have opposite spins. No two electrons in an atom can have same set of all the four quantum numbers as per Pauli’s exclusion principle.

Why can only two electrons have the same spin?

This would violate conservation of energy, and thus cannot happen. Consequently, only two electrons have the same values for the first three quantum numbers, because the two can have opposite spin. This is why each atomic orbital has room for two electrons.
