Title: Francium!! Is this the most reactive metal???
Post by: Seany on 23/05/2007 22:46:26
I have realised that in the Periodic table, Francium is in group one, and is the furthest down.. Does this mean that Francium is the most reactive METAL?

Probably, but it's so unstable that nobody has ever collected enough together to find out.

I'm quite sure there has already been a thread on this subject. However the answer depends on what exactly you mean with "reactive".

Like, reacts with other stuff easily.. Has a vigorous reaction.

Ok, but with wat, and in which conditions? Maybe you intended with water at room temperature? Because if you intended "amount of heat and reaction speed" with oxidizing substances after activation with a flame (for example), then it's magnesium, aluminum. If you mean another kind of reaction (with sulfur, or with chlorine, or nitrogen...ecc.), others metals. It really depends on the reaction you want to consider.

Ermm OK. Nevermind about this topic then. [;)]

I think calculations show that it is probably no more reactive than Caesium, because the electrons near the centre start moving at a speed where relativity is important and this breaks the pattern.
