In this case, 6 valence electrons for each oxygen, so we have 18 total valence electrons.

在这种情况下，每个氧原子都有六个价电子，因此我们总共有十八个价电子。

So we have a total of 2, 4, 6, 8, 10 valence electrons, so I'll make sure I count to 10 as we fill up our molecular orbitals here.

我们一共有2,4,6,8,10个价电子，所以我一边填一边要确认，我数到10。

So in terms of total numbers that we would need to complete our octets and fill our valence shells, we would need 18 electrons.

因此要填满我们的“八隅体“,排满所有的价壳层，我们总共需要十八个电子。

We told you that phosphorous has 5 valence electrons plus 3 from each of the hydrogens, so we have a total of 8 valence electrons.

我告诉过你们磷有5个价电子，另外氢有3个，所以我们一共有8个价电子。
