1.And francium, which I think is more radioactive, is probably very warm.

francium，认为它放射性更强，所以可能非常暖和。机翻

2.So francium would almost certainly be even bigger than cesium, because it's a whole row lower down.

因此， 钫原子尺寸几乎肯定比铯更大，因为它位于元素周期表中铯下一整行。机翻

3.Francium was named after France, was discovered by one of Madame Curie's pupils in 1939, five years after Madame Curie herself died.

钫元素以法国命名，于1939年由居里夫人一个学生发现，距离居里夫人去世已有五年。机翻

4.It might well be colored, as well, because cesium is golden colored so I would not be surprised if francium was red.

它很可能也是有颜， 因为铯是金，所以如果钫是红， 也不会感到惊讶。机翻

5.But, unfortunately, francium is very radioactive and you can't get a nice lump of francium the sort of size that you'd like to throw in water to make the YouTube video of the century.

但遗憾是，铯非常具有放射性，你无法得到一块理想大小铯块，那种你想要扔进水里以制作本世纪最火爆YouTube视频铯块。机翻

6.So I think the melting point of francium will be lower than that of cesium because the melting points go down the group, and because it will be generating heat, almost certainly francium will be liquid at room temperature.

因此， 认为钫熔点会比铯低，因为同一族元素熔点是逐级下降，加之钫会产生热量，几乎可以肯定， 钫在室温下会是液态。机翻
