This is what's called the Bohr radius, and we'll explain - hopefully we'll get to it today where this Bohr radius name comes from, but for now what you need to know is just that it's a constant, just treat it like a constant, and it turns out to be equal to or about 1/2 an angstrom.
它叫做玻尔半径,我们后面会解释,希望我们今天可以讲到,波尔半径这个名称的由来,但现在你们只要记住,它是一个常数,只要把它当做一个常数对待,它等于,或者是1/2埃。
s But it just turns out that the 4 s is so low in energy that it actually surpasses the 3 d, because we know the 3 d is going to be pretty high in terms of the three shell, and the 4 s is going to be the lowest interms of the 4 shell, and it turns out that we need to fill up the 4 s 4s before we fill in the 3 d.
但是结果是,能量较低,4s是第四层最低的,因为我们知道3d在第三层,是非常高的,4s是第四层,最低的,结果是我们在填充3d之前,需要先填充。
