By Atomic Mass
Mendeleev's table was arranged by atomic mass and the periodic table is arranged by protons (atomic number).
The first periodic table was developed in 1869 by Dmitri Mendeleev. He arranged the known elements by atomic mass.
My the Atomic Mass.

No. The modern periodic table is arranged in accordance to increasing atomic number and repeating properties.
The elements arranged according to their atomic number in the table are called periodic table.
by Atomic Mass
The periodic table is arranged by atomic mass. Hydrogen is the lightest element. Its atomic mass is one.
Compared to Mendeleev's periodic table which was arranged my atomic mass, Moseley's was, however, arranged by atomic number.
Mendeleev arranged the elements by increasing atomic mass instead of like today by increasing atomic number.
