Thallium.
Thallium is an element on the periodic table. It's atomic number is 81.Because it is an element, I don't understand what you mean by "its formula".The symbol for Thallium is Tl, so the formula would be Tl...If you want the formula for a compound with thallium, that's a different story.It is not a diatomic element, if that's what you meant.For more information on thallium, go tohttp://en.wikipedia.org/wiki/Thallium
