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.

How many elements are known to man kind?

There are 92 elements that exist in nature*. Every heavier element has decayed before our time.Of course, there are more elements in the periodic table, but they are all synthetic elements-they were made in a laboratory. Theoretically, there is no limit on how heavy an element could become-you can always add a proton to the nucleus. However these synthetic elements exist only for a fraction of a second and only in particle accelerators. There are currently 115 known elements, 112 of which have been confirmed and are named (or in the process of being named).*If you extend the term "nature" to other planets and stars, than you will occassionally find more elements.
