The repulsion between the unbonded pairs is even stronger than repulsion between the shared pairs, so the two hydrogens get pushed a little further to an angle of 104.5 degrees.

剩返的两对电子之前的斥力比共享电子对之间的斥力更强，所以两个氢原子被推得更远形成一个104.5度的角。

Unbonded atoms within a molecule generally like to be as far away from each other as possible, especially if they have the same partial charge as the 2 hydrogens do with their partial positives.

分子内未键合的原子通常喜欢彼此尽可能远离，尤其是当它们具有与 2 个氢的部分正电荷相同的部分电荷时。
