It might be Iodine and Tellurium because Tellurium has a larger atomic weight than Iodine but Iodine has more similar properties with Fluorine and Chlorine so Mendeleev placed them that way to make more sense but at that point the elements were aranged in order of Atomic Mass. Now the Periodic Table is in order of it's atomic number rather than it's atomic mass so it all fits nicely.

What is an atomic number. how is it used to create a periodic table?
The atomic number is the number of protons in the nucleus of an element. It defines the element. No two different elements can have the same number of protons. It is used to lay out the periodic table because the table shows the elements in increasing numbers of protons.
