Hey, lets take this deadly chemical called Cloride and combine it with this metal that explode with water and put it on our food

Or take carbon which is found in everyliving thing, combine it with Nitrogen, most abundant atmospheric gas and end up with Cyanide ( CN ) a deadly poison.
I find it interesting how two elements that work together in nature and are not poisonous, combine to make something so deadly.
Then again take Carbon and Oxygen as Carbon Monoxide and that is also deadly.

Ozone ( O_3 ) - essential for filtering out UV fine at high altitude not so good at ground level
H2O2 - chemical that is deadly to almost all life and will corrode almost anything.
