What is the most lethal non radioactive chemical out there,you know,the sort of stuff that would melt you down in seconds and leave you in a yellow and green mush,iv` been arguing with my friend,im`r flummoxed as to what it is but he says it`s some weird stuff iv`e never heard of,please could you settle the argument,cheers:confused: :confused:

I'd invite you to swallow a couple of grams of cesium, but you wouldn't get beyond putting it in your mouth before your head was converted to a rapidly expanding gas. It's a reactive metal that pulls apart water molecules, freeing hydrogen and producing a crap-ton of heat. Then the hydrogen ignites.

Yay, videos!

Fluorine gas will handily turn your lungs into a mushy puddle in tiny amounts, and some super-concentrated acids could well dissolve your entire body.

*coughs*

Strong alkalis will quickly turn you to soap.

Sodium Azide is a fun one. :)

Dimethyl Murcury is extremely toxic. I'm pretty sure most lab chemists don't mess with that chemical because of it's high toxicity.

Hydrofluoric Acid is also very toxic.
