Why couldn't Mendeleev predict the existence of the noble gases in the periodic table of elements?
He could predict other elements because there was an obvious gap, but he couldn't predict the noble gases because he didn't realize that there was going to be an 18th group since none of them were yet discovered. When he first started organizing the periodic table, the pattern still made sense even without the noble gases.

Why do scientists were frustrated by the organization of the elements before 1869?
Scientists were frustrated because there was no clear pattern or organization to the known elements, making it difficult to predict or understand their properties. This lack of organization hindered the ability to make sense of the relationships between different elements and impeded progress in the field of chemistry.
