And I was out there and the only place you could really get water, except for a few drinking fountains, were from the Evian booths and it talks on-- sand o three fifty for a bottle of water, which is pretty typical of these places, but what was interesting was the fact that this is shipped in from France.

我也去看了,除了几个饮水机之外,唯一可以喝到水的地方,就是依云矿泉水的摊位,而它的一瓶水要3.5美元,这种地方通常都是这个价,但有意思的是,这是由法国进口的

So, in the case of boron plus 1, what we are starting with is the ion, so we're starting with a 2 s electron, 2 s 1 and then we're going to 2 s 1 here.

在正一价硼中，我们面对的是这个离子，本来就应该从，2，s，电子开始，然后这里变成。

So what we'll end up with is boron plus, 1 s 2 2 s 2 1 s 2, 2 s 2, E and what we say is the delta energy or the change in energy as the same thing as saying the energy of the products minus the energy of our reactant here, that's how much energy we have to put into the system to eject an electron.

所以结果应该是正一价的硼，电子排布为，我们说，Δ,也就是，E，的变化量,等于生成物的能量,减去反应物的能量，这就是我们从这个系统中,打出一个电子所需要的能量。
