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

而 francium，我认为它的放射性更强，所以可能非常暖和。

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

因此， 钫的原子尺寸几乎肯定比铯更大，因为它位于元素周期表中铯的下一整行。

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由居里夫人的一个生发现，距离居里夫人去世已有。

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

它很可能也是有颜色的， 因为铯是金黄色的，所以如果钫是红色的， 我也不会感到惊讶。

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.

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

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， 我认为钫的熔点会比铯的低，因为同一族元素的熔点是逐级下降的，加之钫会产生热量，几乎可以肯定， 钫在室温下会是液态。
