>Has anyone here seen a reaction between Francium and water? What's it like?
There's 13g of Francium on the whole planet, so no

It's probably similar to the other alkali metals but not as energetic as Cesium since its highly radioactive. This might be why there's no videos of it because it decays quickly.

>>7664730
You could hypothetically synthesize francium and do it, so maybe.

Also where'd you get this 13g estimate? That's oddly specific.

>>7664781
If there's that little on earth its most likely easy to quantify.

Same with astatine. I think there's roughly 10g on earth as well.

Quickest way to spot a pop-sci faggot

https://en.wikipedia.org/wiki/Francium#Occurrence

"In a given sample of uranium, there is estimated to be only one francium atom for every 1 × 10^18 uranium atoms. It is also calculated that there is at most 30 g of francium in the Earth's crust at any given time."

>>7664781
We can only ever synthesize a few atoms at a time, so appreciable amounts really can't be made within a half life (which I think is 22 minutes)

But even if enough francium were synthesized at any one time, the heat caused by its radiation plus its predicted low melting/boiling point will probably vaporize it before it can even do anything with water

Astatine? You're probably looking at less than 1 gram on the earth at any given time.

With what instrumentation or techniques do people identify individual atoms

Is this bait?

>>7665499
Mass spectrometer?

>>7665519
Given that it seems like a reasonable question if you don't know how rare and unstable Francium is, I'm going to guess "no".

>>7665499
Investigating the decay chain of uranium isotopes allows extrapolation of what any given block of uranium will contain if left to sit.
