Why was Mendeleev’s table incorrect?
In later years, Mendeleev had the habit of making further predictions and named the missing elements after the element above it in the periodic table using the prefix “eka”, as mentioned before, which is a bit weird given the fact that in Mendeleev’s favorite short form of the periodic table, all the eka-names come …
What was wrong with the first periodic table?
In devising his table, Mendeleev did not conform completely to the order of atomic mass. He swapped some elements around. (We now know that the elements in the periodic table are not all in atomic mass order.)

Which of the following is the most significant reason for the lack of a periodic table until nearly 1870?
But the table did not appear in print until 1870 because of a publisher’s delay—a factor that contributed to an acrimonious dispute for priority that ensued between Lothar Meyer and Mendeleev. Around the same time, Mendeleev assembled his own periodic table while he, too, was writing a textbook of chemistry.
Why did the periodic table initially not follow a pattern?
Why did the periodic table initially not follow a pattern? Because some elements had not been discovered yet. Based off a rudimentary periodic table, was Mendeleev able to accurately predict the properties of the newly discovered element discussed here?
