How many elements were there in 1860?
63 elements had been discovered so far.
How many known elements were there in 1789?
How many known elements were there in 1789? Short answer = more than 63 Longer answer = In the 1860's Mendeleev organized the 63 known elements. After this organization there was a boom of new elements being discovered (because we now knew what we were looking for). I'm sure further research would turn up a better answer.
