So what we're going to see is less shielding, which means that it will actually feel a higher z effective.
那么我们将会看到更少的屏蔽,这意味着将会感受到更大的有效核电量。
Not only are we taking away an electron here, but we're also going to decrease shielding, so the electrons that are already in there are going to feel a higher z effective and will be pulling and the atom will be getting smaller.
这不只是因为我们拿走了一个电子,还因为我们这样做会减小屏蔽效应,这样留下的电子,将会感受到更大的有效核电量,也就会感受到更强的吸引力,使得原子变得更小。
Because nutrition is going to be one of the big problems of your generation; how to have enough nutritious food for the population as it grows.
因为营养,对你们这一代人是个大问题,怎样才能确保食物的质和量,能够满足日益增长人口的需求
Expensive stocks move more.
贵的股票的移动量也大。
It turns out, and we're going to get the idea of shielding, so it's not going to actually +18 feel that full plus 18, but it'll feel a whole lot more than it will just feel in terms of a hydrogen atom where we only have a nuclear charge of one.
结果是我们会有,屏蔽的想法,所以它不会是完整的,但是它会比原子核电荷量,吸引力要大很多,只有1的氢原子的。
They're less shielded because they're closer to the nucleus, they feel a greater z effective.
它们受到少的屏蔽,因为它们离原子核更近,它们感觉到一个更大的有效电荷量。
And it turns out that if we have a, for example, for s, a very large z effective or larger z effective than for 2 p, and we plug in a large value here in the numerator, that means we're going to end up with a very large negative number.
结果是如果我们有一个,举例来说对于s一个很大的有效电荷量或者,比2p大的有效电荷量,并且我们将一个较大的值代入计算器,那意味着我们最后会得到,一个非常大的负数。
