A nonpolar covalent bond happens when both atoms have the same strength of electric attraction for the Shared electrons.
两个原子对共用电子对具有相同的引力时，则形成非极性共价键。
Remember, every time we have two electrons that are being Shared, that's a single bond.
还记得，每次我们有两个电子被共用，我们就有了一个单键。
A pair of electrons Shared between two atoms in a covalent bond.
在共价键中被两个原子所共有的一对电子。
Each of the four valency electrons of the carbon atom is shared with one of a hydrogen atom .
碳原子的四个价电子都各与氢原子的一个价电子共用。
Each of the four valency electrons of the carbon atom is shared with one of a hydrogen atom .
