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。
It's a little puzzle piece that says when the green flag is clicked and this is kind ; of like the beginning of a program; when you double click an icon on your desktop this is how something like that is implemented; it's listening for that double click, it's listening for that green flag.

If I had a beaker sitting on the table here and it contained a million blue double stranded DNA molecules and a million red double stranded DNA molecules and I heated it up and added a little base, I'd soon have four million individual strands just floating around in the solution because I've broken up this hydrogen bonding and the DNA molecules fall apart.
假如我这里有一个烧杯 里面,盛有一百万条蓝色DNA双链和,一百万条红色DNA双链,然后我稍微加热一下烧杯,并且加一些碱,很快我就有了四百万条DNA单链,漂浮在溶液里,因为我已经使得氢键断裂,DNA双链也随之打开
