The elements are organised in the Periodic Table of elements by order of ascending atomic number. They are arranged in groups and periods to demonstrate the gradual trends that are characteristic of certain groups of elements.
The different elements are arranged in the increasing order of their atomic number and repeating chemical / physical properties.

Number of protons PLUS number of valence electrons (plus - if needed - number of electrons in inner shell).
there are lots of chemical symbols about 110 but they are only used for elements not compounds.
Fieldsets are used to organize form elements.
The properties of elements are found to be periodic when arranged according to atomic number. Hence atomic number is considered as base for arranging the elements.

They used atomic number instead of Atomic Mass to organize the elements
