天然存在或者实验室制造的纤锌矿型氮化硼和朗斯代尔石数量很少，直到现在，也没有一个人发现它们令人吃惊的硬度。

Only small amounts of wurtzite boron nitride and lonsdaleite exist naturally or have been made in the lab so until now no one had realised their superior strength.

So in the case of boron here, what we're starting with is the ion, and now we're going to pull one more electron out.

那么在硼的情况下，我们应该从这个离子开始，现在我们要再拿走一个电子。

So between b e, and b, between n and o, magnesium and aluminum, and then phosphorous and sulfur, what we see here is that we're kind of going down, or quite specifically, we are going down.

比如从铍到硼，从氮到氧，从镁到铝，从磷到硫，我们在这些地方看到有点下降，或者可以明确地说，我们确实在下降。

So, we have beryllium in the first case here, it has four electrons, that's how we know it's beryllium, boron has five electrons.

那么我们将铍作为第一个例子，它有四个电子，这也是我们为什么能知道它是铍的原因，硼有五个电子。
