Each of these electron pair so that electron pair would be represented as a covalent bond.

这些电子对中的每一个电子对都将表示为共价键。

On the other hand, a material with all its electrons paired up is slightly repelled by a magnetic field, because when the electrons move around in an atom, they make magnetic fields of their own, which repel other magnets.

另一方面，所有电子都配对的材料对磁场有轻微的排斥，因为当电子在原子内部运动时，它们自身产生了一个磁场，这个磁场排斥了其他磁体。
