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。
As such, it governs-among other things-the energy levels of an atom formed from negatively charged electrons and a positive nucleus.
就此而论，它控制由带负电荷的电子与正电荷原子核的形成的原子能级。
It has a nucleus at the center charged positively.
中心有个带正电的原子核。
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。
In a neutral atom, the protons in the nucleus are balanced by the electrons. An atom that has gained or lost electrons becomes negatively or positively charged and is called an ion.
在中性原子中，电子数和原子核的正电荷数相等，但有些原子可以拥有比原子核的正电荷更多或更少的电子，从而原子就带上负的或正的电荷，这类带电的原子称为离子。
The overlapping cylinder model(OCM) is used in this letter to describe the rapidity (or pseudorapidity) distributions of charged particles produced in nucleus-nucleus collisions at high energies.
应用重叠柱模型描述了高能核-核碰撞中带电粒子的快度（或赝快度）分布。
As we pass an atomic nucleus, to us on the electron it appears as a large charged body moving in the opposite direction.
当穿过原子核后，我们会看到那个电子如同一个带电体朝相反的方向移动。
The nucleus consists of uncharged neutrons and positively charged protons. negatively charged electrons travel around the nucleus in their orbits, similar to the way planets moving around the sun.
细小的原子核内含不带电荷的中子及带正电荷的质子，而带负电荷的电子则沿轨道环绕原子核运行，情况就好像行星环绕太阳运行一样。
The pseudorapidity distributions of charged particles produced in high-energy nucleus-nucleus collisions are studied using Liu's cylinder model.
用柱模型研究了高能核-核碰撞中产生的带电粒子的赝快度分布。
The atom is a basic unit of matter consisting of a dense, central nucleus surrounded by a cloud of negatively charged electrons.
原子是物质的基本单位组成了一个密集，中央核周围有云带负电荷的电子。
The atom is a basic unit of matter consisting of a dense, central nucleus surrounded by a cloud of negatively charged electrons.
