If you are referring to the Periodic Table of the Elements, it is arranged by the atomic number of each element, increasing from Helium, which has an atomic number of 1 through Ununoctium, which has an atomic number of 118.
According to atomic number.
Mendeleev's version of the Periodic Table was organized by increasing mass. The modern periodic table is now organized by atomic number.
He organized the elements by the increasing order of the atomic mass.
Yes.The modern periodic table is organized by atomic number. The elements properties are found to be periodic.

The current Periodic Table is organized by each elements atomic number. The atomic number is the number of protons in the nucleus of the atom of each element.
By atomic number.
On atomic number.
The periodic table was first organized by atomic mass. However, after the discovery of isotopes and inconsistencies around this method, it was later rearranged based on atomic number, which reflects the number of protons in an atom's nucleus.
Dmitri Mendeleev

On very early versions of the Periodic Table the elements were organized by atomic mass, because it was measurable and the concept of atomic number was unknown. After Rutherford and Bohr developed their model of the structure of the atom, the Periodic Table was reorganized by atomic number (which caused a few elements to swap positions).
