People did not fully agree with Mendeleev's Periodic Table because he arranged elements by Atomic Mass rather than atomic number, leading to some inconsistencies. For example, elements like iodine and tellurium appeared out of order based on their properties. Additionally, Mendeleev left gaps for undiscovered elements, which some critics viewed as a sign of weakness in his theory. His ideas were eventually validated with the discovery of these elements and the establishment of the atomic number as the organizing principle for the periodic table.
