The problem of arrangements in the first Periodic Table, created by Dmitri Mendeleev in 1869, was primarily related to the placement of elements based on atomic weights rather than atomic numbers. This led to some inconsistencies, such as iodine being placed before tellurium despite its higher atomic weight. Mendeleev also had to leave gaps for undiscovered elements and predict their properties, which created uncertainty. Ultimately, the discovery of atomic numbers later resolved these issues, leading to the modern periodic table's arrangement.

Is the periodic table arranged?
The Periodic Table of elements has gone through several arrangments, but the current (and correct) arrangement goes from lowest to highest atomic number (number of protons). i.e. Hydrogen has 1 proton, Helium has 2 protons, etc.
