In mendeleev's periodic table there were gaps for undiscovered elements.modern periodic table maintains uniformity. Mendeleev found that, when all the known chemical elements were arranged in order of increasing atomic weight, the resulting table displayed a recurring pattern, or periodicity, of properties within groups of elements. Animation of the periodic table. Features of mendeleev's periodic table: At this time, other chemists. In the modern periodic table, elements are in order of atomic number in periods and groups. Given the number of properties for each element and its many applications, how the table should look has long been a subject of debate.
