Why is it safer to lick Lithium than Caesium?

Radon is a gas. I’d like to see you lick that. Same for the halogens, the noble gases, nitrogen, oxygen hydrogen and probably some I forgot.

The alkali metals get more strongly reactive the higher their atomic number.

Lithium will react pretty violently with the water in your saliva, but cesium will blow up your head. If you get enough of it wet to cover your tongue

I thought it was the other way around. Thanks for correcting me.
