They are placed in order based off of their mass number or atomic weight.
The modern Periodic Table is made according to the atomic numbers. The groups are made considering the properties of elements. The periods show the number of energy levels.

The elements are arranged with increasing atomic number
Atomic Number
newlands arranged the elements in the periodic table in order of relative atomic massNewlands arranged elements in group of eight like musical notes.
They have simliar properties and same elements although later on more elements were added to the modern periodic table.=Both periodic tables have elements grouped by similar properties. Mendeleev's periodic table had elements arranged in order of increasing atomic mass in columns with similar properties. While many of the elements are in order of atomic mass on the modern periodic table, some are not, as the modern table has elements arranged in order of increasing atomic number.=
elements are listed in the periodic table in order of increasing atomic number
The atomic weight, or the number of protons.
Element's atomic number decide its place in periodic table. They r arranged in increasing order.
the elements in the modern periodic table are arrange in the increasing order of their atomic numbers.
The elements are arranged with increasing atomic number
Mendeleev arranged the elements in a table in the increasing order of atomic masses and repeating periodic properties. In the modern long-form of periodic table, the elements are arranged in the increasing order of atomic number and repeating periodic properties.
The periodic table contain all chemical elements, placed in a rational order.
Elements are arranged on the Periodic Table in the order of the atomic number, in groups and periods.

The short answer is yes - the periodic table is about order.
The order of the periodic table is made according to the atomic weights of the elements. The number of protons and neutrons in the nucleus make the atomic weight. Protons make the elements in order of the periodic table.
the elements in the modern periodic table are arranged according to their increasing atomic number.
