硫的读音

但是，没有人知道硫来自何处。

But no one knew where the sulfur came from.

通常，我们称这些污染物为悬浮微粒，它们包含烟尘以及氮硫与进入大气的其他物质的混合物。

These pollutants are called aerosols and they include soot as well as compounds of nitrogen and sulfur and other stuff into the air.

因此，如果我们来比一下硫和氧，氧应该有更高的电负性，而在这个分子中它确实有负的电荷。

So, if we compare the sulfur to the oxygen, the oxygen it turns out is more electronegative and that is what holds the negative charge in this molecule.

OK, so now we've got, taken an electron from that sulfur, put it here, an electron from that sulfur, put it here.

现在我们得到的是，从硫那儿得到一个电子，放在这儿，一来自于硫的电子，放在这儿。

times 7, plus we have 6 in the sulfur, and oxygen is right above sulfur, so that also has 6.

二乘上七，加上硫的六个，而氧在硫的正上方，因此也有六个。

2 3 Well, son of a gun, one, two, three, four, five, six, sulfur, We've got six. We've used all the electrons.

真见鬼，4，5，6，硫，共六个，我们已经用掉了所有的电子。
