There will normally be one electron circling about the hydrogen nucleus.
正常情况下，有一个电子，围绕着氢原子核运转。
Heavy water is heavy because the hydrogen in it weighs twice as much as ordinary hydrogen (it has a proton and a neutron in its nucleus, instead of just a proton).
重水之所以重是因为水中氢的重量是普通氢的两倍（它的原子核中有一个质子和一个中子，而不仅仅是一个质子）。
That is the electron in its lowest orbit, to the nucleus of atomic hydrogen.
那就是氢原子原子核外电子，最低轨道到情况。
Heavy water gets its name because it contains deuterium, a form of hydrogen that has a neutron in its nucleus as well as the usual proton and thus weighs twice as much as the ordinary sort.
重水因含重氢而得名。重氢是氢原子的一种，其原子核中含有一枚中子，加之正常氢元素中的质子，重量为一般氢原子的两倍。
We're going to be looking at the solutions to the Schrodinger equation for a hydrogen atom, and specifically we'll be looking at the binding energy of the electron to the nucleus.
我们将研究下氢原子薛定谔方程的解，特别是电子和核子的结合能，我们将研究这部分。
Because what it tells is that we can figure out exactly what the radius of an electron and a nucleus are in a hydrogen atom.
我们可以，准确的算出，氢原子中，电子。
So in hydrogen atom a, I'll depict that here where the nucleus is this dot, and then the circle is what I'm depicting as the wave function.
在氢原子A里，我在这里把原子核画成一个点，这圆就是波函数。
A deuterium atom is a hydrogen with an extra neutron in its nucleus.
重氢是原子核中多一个中子的氢。
