And then that hydrogen is interacting with another electronegative atom like that.

然后氢与另一个像这样的电负性原子相互作用。

And so in this case, we have a very electronegative atom, hydrogen, bonded-- oxygen, I should say-- bonded to hydrogen.

所以在这种情况下，我们有一个非常负电的原子，氢，键合——氧，我应该说——键合到氢上。

And so the mnemonics that students use is FON. So if you remember FON as the electronegative atoms that can participate in hydrogen bonding, you should be able to remember this intermolecular force.

所以学生使用的助记符是 FON。所以如果你记得 FON 是可以参与氢键的电负性原子，你应该能够记住这种分子间力。

And what some students forget is that this hydrogen actually has to be bonded to another electronegative atom in order for there to be a big enough difference in electronegativity for there to be a little bit extra attraction.

有些学生忘记的是，这个氢实际上必须与另一个带电负性的原子结合，以便在电负性方面有足够大的差异，从而产生一点额外的吸引力。
