The periodic table is arranged (1) by increasing atomic number; (2) into groups of elements with similar chemical properties; (3) into periods of elements with the same number of electron shells.
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.
Many more elements are known today then when Mendeleev laid out his table. In addition, he arranged his table by atomic mass and there are places in the periodic table where mass does not always increase. An example is between tellurium and iodine.
By atomic number: Elements are arranged in order of increasing atomic number, which is the number of protons in the nucleus. By chemical properties: Elements in the same column (group) typically have similar chemical properties. By electron configuration: Elements are organized based on the arrangement of electrons in their atoms. By periods (rows): Elements are grouped into rows based on the number of electron shells. By blocks: Elements are classified into s-block, p-block, d-block, and f-block based on the type of subshell being filled with electrons.

Arsenic did not create the first periodic table. The first periodic table was created by Dmitri Mendeleev, a Russian chemist, in the 1860s. Other scientists had organized elements in other ways prior to the invention of Mendeleev's periodic table, but the other methods were criticized and did not catch on.
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.

Sounds like the Periodic Table of the elements.
The vertical columns on the periodic table are called groups. The table is arranged in such a way that all elements in the same group are similar and have the same number of valence electrons.
The arrangement of all known elements in order of their atomic numbers is called the periodic table of elements. The periodic table organizes elements based on increasing atomic number, showing similarities in properties and periodic trends across rows and columns.
Periodic table can be classified as:MetalsTransition elementsNon-metalsThey occupy different groups.
By atomic number: Elements are arranged in order of increasing atomic number, which is the number of protons in the nucleus. By chemical properties: Elements in the same column (group) typically have similar chemical properties. By electron configuration: Elements are organized based on the arrangement of electrons in their atoms. By periods (rows): Elements are grouped into rows based on the number of electron shells.

The periodic table is just a way of grouping elements according to their atomic numbers. It helps scientists to understand why different elements react in different ways.
