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.

， 的原子尺寸几乎肯定比更大，为它位于元素周期表中的下一整行。

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

它很可能也有颜色的， 为色的，所以如果红色的， 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，非常具有放射性，你无法得到一块理想大小的块，那种你想要扔进水里以制作本世纪最火爆的YouTube视频的块。

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.

， 我认为的熔点会比的低，为同一族元素的熔点逐级下降的，加之会产生热量，几乎可以肯定， 在室温下会液态。
