By physical and chemical properties
The elements are arranged in order according to the atomic number. The periodic table is arranged so that the elements in each column have similar chemical properties.
On the periodic table there are squares. Each square corresponds to one element.
The atomic number of each element is on the periodic table. The elements are arranged on the periodic table in order of increasing atomic number.
he arranged his Periodic Table by each elements Atomic Mass
Elements are arranged in order of increasing atomic number. The atomic number is the number found at the top of each box on the Periodic Table. The atomic number is the number of protons in the nucleus of each atom of each element.
Each square in periodic table contains following: 1. symbol of the element 2. atomic number
because they have different opinions about each other

its atomic number
That's because gold has 79 protons and mercury has 80 protons. The elements in the periodic table is arranged by the proton count.
