Barnyard1 OK. The change is, well, on Barnyard 1 it looks much the same as it did for Barnyard.

也就是solve1和,做出的变化就是在Barnyard1中。

So path number 1 went from i, f let's call this path up here. went to f, and this is how much energy change there was.

从i出发，经过路径1到达，能量的变化是这么多。

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。
