Dmitri Mendeleev
periodic table. He organized the elements based on their atomic mass and observed that elements with similar properties appeared at regular intervals. This arrangement laid the foundation for the modern periodic table we use today.
Mendeleev is usually credited as the first person to do so. Subsequently, chemists learned to arrange the elements by atomic number rather than atomic mass.
Mendeleev arranged the known chemical elements in a table according to increasing atomic mass and similar chemical properties. This arrangement led to the periodic table of elements, where elements with similar properties fall into the same column or group. This organization allowed Mendeleev to predict the properties of undiscovered elements and leave spaces for them in the table.

Mendeleev arranged the elements in the periodic table according to their atomic masses.
By doing it this way, you can arrange them in a fashion in which you can predict their reactivity by the row that they're in. This is because they are lined up to account for a visualisation of how much of the energy level is filled with electrons
Dmitri Mendeleev arranged the elements in his periodic table by increasing atomic mass because he noticed a periodic pattern in properties repeating every 8th element. This arrangement allowed him to predict the properties of undiscovered elements and left gaps for them in his table.
The verb of arrangement is arrange. As in "to arrange something"
The modern Periodic Table arranges elements based on properties. These properties include valence electrons of the elements and density for example.
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 elements are arranged in order of increasing atomic number. Also elements in the same column have simmilar properties.
