And when we do that we can see this curve, this probability curve, where we have a maximum probability of finding the electron this far away from the nucleus.

当我们这样做时，我们可以看到这个曲线，这个概率分布曲线，这里有发现,电子的最大概率。化学原理课程节选 : 麻省理工公开课

And then the potential energy, the energy is stored here due to the coulombic force of attraction between the electron and the nucleus.

然后说势能,位能其实就是,由电子和原子核之间的库仑引力而形成的能量。固态化学导论课程节选 : 麻省理工公开课

And the way that we'll do this is starting with talking about the discovery of the electron and the nucleus here.

在这之后,我们就可以通过,经典力学来描述一个原子。化学原理课程节选 : 麻省理工公开课

And the reason that they're the least sheilded is because they can get closest to the nucleus, so we can think of them as not getting blocked by a bunch of other electron, because there's some probability that they can actually work their way all the way in to the nucleus.

它们最不容易被屏蔽的原因,是因为他们可以更加接近原子，所以我们可以认为它们,最不容易被其它原子阻挡住，因为它们有一定的概率,离原子核非常近。化学原理课程节选 : 麻省理工公开课

Although the transplanted nucleus enters the egg properly imprinted, reprogramming messes this up.

ECONOMIST: Cloning around

A neutron is simply a neutral particle in the nucleus of an atom.

简单说，中子就是原子核内一种不带电粒子。

"It's been important to keep the nucleus as even to replace the few we have lost is a big ask, " he said.

BBC: Histon boss rules out more exits

"All genes are encoded by DNA and the DNA is present in the chromosomes in the cell nucleus and telomeres, they are the ends of the chromosomes and they have an important function to protect the chromosomes and maintain the integrity of the chromosomes."
