「鈹」的拼音

绿宝石其实是一种铍铝硅酸盐，而它的颜色则来自于微量的铬元素。

Beryl is a beryllium-aluminum silicate, and its color comes from small amounts of chromium.

如同所有的电视一样，液晶显示器的塑料外壳经过溴化阻燃剂处理，内部线路用了各种有毒重金属，如镉，铬，锑，铍。

As with all TVs, LCDs have plastic shells treated with brominated flame retardants and wiring that has various toxic heavy metals such as cadmium, chromium, antimony and beryllium.

仅仅考虑周期性规律，是无法理解这个问题的，这里显示硼的电离能，实际上比铍的要小。

And the glitch that doesn't make sense just through periodic trends, is that it turns out that the ionization energy of boron is actually less than the ionization energy up beryllium.

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。

Look at beryllium 2 plus, very tiny, charge plus two.

例如铍二正离子，非常小，带2个单位正电。
