the answer is mendeleev
All groups in the periodic table contain chemical elements.
the elements in the modern periodic table are arrange in the increasing order of their atomic numbers.

That would be Dmitri Mendeleev.
I suppose that you think to chemical elements, not to compounds. Dimitri Mendeleev is credited for the creation of the periodic table of elements.
Atomic Number
The periodic table is based on an element's number of atoms. The elements are arranged from least to most number of atoms.
Dmitri Mendeleev was a Russian chemist who proposed the Periodic Law. He published the first periodic table of the chemical elements in 1869, based on the increasing atomic masses of the different elements.
All groups in the periodic table contain chemical elements.
the elements in the modern periodic table are arrange in the increasing order of their atomic numbers.
I can find only two types The Mendeleves Periodic table based on Atomic weight of elements and The Modern Periodic table based on Atomic number of elements.
periodic table of elements
The modern Periodic Table arranges elements based on properties. These properties include valence electrons of the elements and density for example.
the number of protons.
