    Explain Pair Spin
Click For Summary
SUMMARY

The discussion clarifies that electron pairing in atoms is not due to spin allowing like charges to stay together, but rather the result of energy states. The attraction of electrons to the nucleus is stronger than the repulsion between electrons. Specifically, a configuration with one spin-up and one spin-down electron in the same orbital has lower energy than configurations where both electrons have the same spin. This energy difference drives the pairing of electrons in atomic structures.

I never understood this how do 2 like charges stay together, the electro is it like eddy currents or something

Spin doesn't allow electrons to stay together. I assume that you're talking about electrons in an atom. What happens is that the attraction of an electron to the nucleus is a bit stronger than the repulsion between the electrons. The bound state of the electrons and nucleus has a lower energy than the unbound state.

Pairing happens because the configuration with a spin up and spin down electron in a particular orbital state has lower energy than the configuration where one of the electrons is in that state and the other electron has the same spin and sits in the next higher energy state.
