  • If you had one negative number in it, then the product would be a negative number and, if you took a root of that, then you might get an imaginary number.

    如果这当中有一个负数,乘积就会变成负的,如果你对一个负数开根号,你就会得到一个虚数

  • It's going to run through the loop, accumulating the answers, but because I'm subtracting, x it's just going to keep making x more and more negative as it goes along, again it's off into an infinite loop.

    它一直在循环,不断的累加答案,这是因为我一直在对x做减法,这使得作为负数的,变的越来越小,又进入一个无限循环了。

  • So you don't want to put in a negative energy, that's not going to help you out, you need to put in positive energy to get an electron out of the system. So that's why you'll find binding energies are always negative, and ionization energies are always going to be positive, or you could look at the equation and see it from there as well.

    因为这对电离没有帮助,你需要一个正的能量,使得电子脱离这个系统,这就是为什么你会发现,结合能总是负的而电离能总是正的,或者你们看这个方程也可以发现这一点。

  • it's an easy calculation -- we're just taking the negative of the binding energy, again that makes sense, because it's this difference in energy here. So what we get is that the binding energy, when it's negative, the ionization energy is 5 . 4 5 times 10 to the negative 19 joules.

    这个计算很简单-我们,只需要取结合能的负值,同样这很容易理解,因为这就是这的能量差,所以我们得到的就是结合能,当它取负值,电离能就是5。45乘以。

  • So, we were talking, however, about energy in terms of electron affinity, so we can actually relate electron affinity to any reaction by saying if we have this reaction written as here where we're gaining an electron, we say that electron affinity is just equal to the negative of that change in energy.

    但是,我们现在讨论的能量,是电子亲和能,因,此我们可以将电子亲和能,与任何反应联系起来,只要我们将反应写成这种得到电子的形式,我们说电子亲和能就等于,反应前后能量变化的负值。
