Hmmmm. In 1700, only 12 elements were known. In 1800, 24 were known. By 1900, 80 were known.
Where do these questions come from? Certainly not history, in my opinion.
So would it be the "knowledge" gained from time through time?
Perhaps your teacher wants you to know the impact of the periodic table discovery on the discovery of the elements in the 1800's. Otherwise, I have no idea.
Would it be experimentation and observation being done by the alchemists all of a sudden.
Sara: BAck to my first post, there was NOT a rapid discovery in the 1700's. IT was in the 1800's. IT was largely the result of the discovery of the periodicity of the elements. But it was NOT in the 1700's.
gotcha, thanks
