Electron structures

Postby Marty Hockey » Sat Oct 19, 2019 7:37 pm

I understand that if 2 electrons are paired they have opposite spin, and if they're parallel they have the same spin, but what makes the electrons paired or parallel?

Electrons are paired if they're in the same orbital and parallel if they're in separate orbitals and have the same spin

Yes! When electrons have opposite spin, they are paired and thus the orbital is more balanced and stable. Additionally, if electrons have parallel spin, they are unpaired and ready to bond with other elements. The reason for this is the Aufbau Principle or Building Up principle, in which we fill up each orbital with one spin-up electron before adding the spin-down electrons.

Remember that electrons will behave in whatever way is most stable to add onto the first person's response.

Each orbital can hold a maximum of 2 electrons, and the two electrons in the same orbital have opposite spins.
