Francium is extremely reactive, but it's so rare that most of us will never encounter it.
In my experience, Mercury is pretty dangerous too. It can cause serious health issues and it's found in everyday items like thermometers!
I'd say Polonium-210. A tiny amount can be lethal, and it's famously known for being used in high-profile poisonings!
