paired and parallel

[Funmi Baruwa]

What does it mean when you say two electrons are paired and two are parallel?

[Faaizah Arshad 1H]

Two electrons in the same orbital will be paired because they must have opposite spins. One will have an up spin and the other a down spin. Electrons in different orbitals can be parallel because they can have the same spin. Electrons in the same orbital cannot be parallel because that would oppose the Pauli Exclusion principle that states that no two electrons can have the same four electron quantum numbers because two electrons in the same orbital must have opposing spins.

[Kiyoka Kim 3C]

When two electrons are paired they have opposite spins. When two electrons are parallel they have the same spin.

[Kelly Tran 1J]

When two electrons are paired, it means that they are in the same orbital and will have opposite spin (Pauli Exclusion Principle) where one electron will be spin up and the other will be spin down.
When two electrons are parallel, it means that they occupy different orbitals and will have the same spin (Hund's Rule) where both electrons will either be spin up or spin down.

[Adam Bustamante 1I]

Paired electrons means that one will be spin up and the other spin down whereas a parallel spin means there's only one electron in each shell with both spin up.

[Jordan_OBrien_2k]

When an electron is paired that means that their are two with opposite spin. When it is parallel, this means that they have the same spin. Electrons with the same spin cannot be in the same orbital of the same subshell according to the Hund's rule

oh okay so spin and parallel and paired electrons go hand in hand. thank you

Paired electrons are in the same orbitals, meaning that all orbitals must have one electron already, and that they are spinning in opposite direction. Parallel electrons mean that they are spinning in the same direction, meaning that the electrons are filling up the orbitals (Hund's rule) before fully occupy the orbital with two electrons. They are spinning in a parallel direction in different orbitals as it is more stable.

[Funmi Baruwa]

thanks!!

[805593945]

Paired electrons are in the same orbital. This only happened once each orbital already contain at least one electron, as stated by Hund's rule.

Parallel electrons spin in the same directions but in different orbitals because of the electron repulsion.

[David Liu 1E]

paired electrons and parallel spin are different! paired electrons are the 2 that would be in the ml orbital with opposite spins (-1/2 and 1/2) and parallel electrons are ones that have the same spin meaning they're definitely not paired
