Because the paired electrons'spins are opposite, their magnetic fields cancel.
2.
As a result of having non-paired electrons in both spin states coupled together, this compound exhibits antiferromagnetism.
3.
Another difference is that the barrelene reaction requires the intersystem-crossing ( ISC ) to provide paired electrons and a new sigma bond.
4.
The barrier is thin enough that electrons, or in the superconducting state, Cooper-paired electrons, can tunnel through the barrier at an appreciable rate.
5.
Because of its unpaired electrons, triplet oxygen reacts only slowly with most organic molecules, which have paired electron spins; this prevents spontaneous combustion.
6.
As they had before a nearly closed filled p orbital ( 5 instead of 6 electrons ), the two paired electrons now sort of close off both orbitals.
7.
In chemistry, the class of electron donors that donate not just one, but a set of two paired electrons that form a covalent bond with an electron acceptor molecule, is known as a Lewis base.
8.
In chemistry, a class of electron acceptors that acquire not just one, but a set of two paired electrons that form a covalent bond with an electron donor molecule, is known as a Lewis acid.
