Henry Gwyn-Jeffries Moseley, an English physicist
Dmitri Mendeleev arranged the known chemical elements in a table according to their increasing atomic mass.
Mendeleev arranged the elements in the periodic table according to their atomic masses.
according to the chronicles Mendelleff first arranged the elements in increasing atomic number
The Periodic Table of Elements.
The elements are arranged in order of increasing atomic number. Also elements in the same column have simmilar properties.
the elements in the modern periodic table are arrange in the increasing order of their atomic numbers.
atomic numbers
In Mendeleev's periodic table the elements are arranged in increasing atomic mass and repeating properties whereas in in the modern periodic table the elements are arranged in increasing atomic number and repeating properties.

The periodic table used to be arranged by increasing atomic mass. Now, it is arranged by increasing atomic number (number of protons in an atom of element).
He arranged the elements in the increasing order of atomic mass and repeating properties so that it is easy to study the properties / reactivities of the elements.
The Modern Periodic Law states that there will be a periodic repetition of properties when the elements are arranged according to increasing atomic number.
