So that means that the more stable molecule is going to be this molecule here, which actually puts the negative charge on be more electronegative atom.
因此这意味着更稳定的分子,应该是这一个,它真正把负的电荷放到了,电负性更高的原子上。
Often what you'll see is not a table based on this definition, but something that's called the Pauling definition of electronegativity, but it's exactly the same idea and the same trend as this more numerical way to think about what the meaning of electronegativity is.
通常你看到的表格一般都不是基于这种定义的,而是基于,鲍林定义的电负性,但在意义上是相同的,并且满足同样的周期性规律,当和这种这种更数值化地理解电负性的定义,作对比时。
You bring somebody in the sleep lab, you put electrodes on their scalp and you see what these-- what sort of electrical activities you get in the brain.
把人叫来睡眠实验室,把电极贴在他们的头皮上,你就能看到-,他们有什么脑电活动。
If you put the electrodes in the right position and you measure in the right way you can detect the electrical activity of the heart and record it on a strip recorder like this one shown here, or display it on a computer.
如果将电极放置正确,并采用正确的方式检测,就能检测到心脏的电活动,并将它记录在像这样的长图记录仪上,或者显示在电脑上
So, when we're talking about the idea of electronegativity, essentially what we're talking about is the ability for an atom to attract electron density from another atom.
那么,当我们在讨论电负性这一概念的时候,本质上我们讨论的是一个原子的吸引能力,用来吸引另一个原子的电子密度的。
Next time maybe we'll charge it up before class.
下一次或许我们,会在课前把它充上电。
