electrons信息详情
n.[物]电子（electron的复数形式）
caesium electrons───铯电子
valence electrons───[化] 价电子
excites electrons───激发电子
antimony electrons───锑电子
tellurium electrons───碲电子
samarium valence electrons───钐价电子
fluorine valence electrons───氟价电子
outermost electrons called───最外层的电子叫做
valence electrons periodic table───价电子周期表
Most things are balanced - with equal numbers of electrons and protons.───大部分物体都是电荷平衡的——含等量的电子和质子。
Under certain conditions, electrons can behave like waves rather than particles.───在某些条件下，电子能像波而不是粒子那样运动。
Inert gases like neon and argon have eight electrons in their outer shell.───像氖和氩这样的惰性气体，在它们的外电子层有8个电子。
The result was a flow of electrons around the edge of the material, like skaters circling the perimeter of an ice rink.───这样造成的结果就是一些电子不断绕着物质边缘流动，就像是滑冰的人在绕着整个场地一圈圈滑行。
Just as the planets revolve about the sun, planetary electrons are thought of as revolving about the nucleus.───正像行星围绕太阳转一样，行星般的电子被认为是围着原子核转的。
This requirement is equivalent to being able to treat the electrons as if they were free.───这个要求与下列情况相当，即可以把电子当作自由的来处理。
A fundamental rule which must be obeyed in placing two or more electrons in the orbits of an atom is the exclusion principle.───当两个或更多电子进入原子中的轨道时，必须遵循的基本规律是不相容原理。
When the total number of protons equals the total number of electrons, the body as a whole is electrically neutral.───当质子总数等于电子的总数时，这个物体就整体来说是电中性的。
On this basis, that the only particles in nature are electrons and protons, it seemed to me that the holes would have to be the protons.───在这个基础上，自然界中仅有的粒子是电子和质子，这告诉我这种空穴只能是质子。
Electrons are negatively charged with electricity, protons are positively charged.
Atoms consist of positively-charged protons, negatively-charged electrons and neutral particles called neutrons.
Electrons are negatively charged with electricity.
Electrons and protons are atomic particles.
The electron microscope uses a beam of electrons to produce images at high magnifications.
As these electrons are negatively charged they will attempt to repel each other.
arena, arenas * circus, circuses * electron, electrons.
Under certain conditions, electrons can behave like waves rather than particles.
Atoms are made up of electrons and protons.
