They do not like uncertainty, so that may be resolved with this agreement, but they also do not like it if there are too many mouths to feed, too many demands on the table."

VOA: standard.2010.05.13

And this is the same periodic table that you're going to get in your exams, so it's good to practice doing your problem-sets with that periodic table so you're not relying on having the double check right there of seeing what the electron configuration is.

这也是你们考试时会用到的相同的表,这样你们就不会，所以使用周期表来做问题集,是很好的练习,这样你们就,不会依赖于再次确认,电子构型是什么了。

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。

I look at the plate on my kitchen table, it's not perfectly round, it's got imperfections; but suddenly I start thinking about circles, perfectly round objects.

我看着我餐桌上的盘子,它不是正圆的,它不完美,但是我马上就可以想到圆圈,正圆的东西

And in terms of doing this for your homework, I actually want to mention that in the back page of your notes I attached a periodic table that does not have electron configurations on them. It's better to practice doing electron configurations when you cannot actually see the electron configurations.

关于你们的作业，是在你们讲义的后面的页,我附上了一张,没有给出电子构型的周期表,最好联系一下做出电子构型,当你们实际上看不到,电子构型的时候。
