And, it involves a single electron orbiting a positively charged nucleus.

包含了一个单独的电子轨道，一个带正电荷的核。

We start with atoms — each with a distinctive positively-charged nucleus and a distinctive array of negatively-charged electrons (think periodic table).

我们开始于原子。每个原子有一个独特的带正电荷的原子核和一些带负电荷的电子(回忆一下因素周期表)。

A unit of matter, the smallest unit of an element, having all the characteristics of that element and consisting of a dense, central, positively charged nucleus surrounded by a system of electrons.

物质的单位、元素的最小单位，有该元素的全部特征，由中部密集的、带有正电的原子核及绕原子核的一系列电子组成。

According to this theory, the atoms consist of a positively charged nucleus surrounded by a stream of electrons kept together by attractive forces from the nucleus.

根据这个理论，原子由一个带正电荷的核组成,由于来自核的吸引力,电子流围绕在核的周围。

So, what we're looking at here is the force when we have two charged particles, one positive one negative -- here, the nucleus and an electron.

我们现在研究的是,一正一负俩个带电粒子之间的,作用力-在这里。

One effect of the beam is to polarise the cloud of electrons surrounding each rubidium nucleus, meaning that part of the atom becomes a negatively charged pole, and part a positively charged pole.
