In ancient Greece, Aristotle postulated that there were four elements (fire, water, earth, air) and arranged these accordingly. Later on when science began to theorize (and later prove) the existence of atomic elements without the benefit of knowing the subatomic properties involved, people sorted them in many different ways.
In 1829 Döbereiner proposed the Law of Triads: The middle element in the triad had atomic weight that was the average of the other two members.
The English chemist John Newlands, noticed in 1865 that when placed in order of increasing atomic weight, elements of similar physical and chemical properties recurred at intervals of eight, which he likened to the octaves of music. As knowledge about subatomic particles increased, this system proved unreliable and fell into disfavor.
The modern Periodic Table of elements which is based on both atomic weights and chemical properties was developed by Dmitri Ivanovich Mendeleev in 1869. Four months later, a German professor Julius Lothar Meyer independently developed a periodic table similar to Mendeleev's.
However, Mendeleev plotted a few elements out of strict mass sequence in order to make a better match to the properties of their neighbors in the table, corrected mistakes in the values of several atomic masses, and predicted the existence and properties of a few new elements in the empty cells of his table. Mendeleev was later vindicated by the discovery of the electronic structure of the elements in the late 19th and early 20th century.
Mendeleev's periodic table also successfully predicted the future discovery of several elements, and has thus become the de-facto standard for the organization and display of the elements.

Dmitrii Mendeleev is generally credited for arranging the first periodic table. It was first presented to the Russian Chemical Society in 1869. He arranged elements according to increasing atomic weight in vertical rows so that the horizontal rows contain 'analogous' elements (generally weights that increase in common increments).
Dmitri Mendeleev is credited as the first person to arrange the elements in a table based on their Atomic Mass and chemical properties, which led to the creation of the periodic table in 1869.
The shell model explains the periodic table. It describes how electrons are arranged in energy levels (shells) around the nucleus, influencing the chemical properties and behavior of elements. This organization of electrons into shells follows patterns that are reflected in the periodic table.
The empty spaces in the periodic table are reserved for elements that have not yet been discovered or synthesized. These gaps allow for predictions of the properties of these yet-to-be-discovered elements based on their positions in the table and their relationships to neighboring elements.
The symbols of elements are derived from their names in various ways, often using the first letter or first two letters of the element's name, in a standardized manner based on the element's English or Latin name. For example, the symbol for sodium is Na, derived from the Latin name "natrium." You can find the symbols of elements on the periodic table of elements.
This periodic pattern is known as the periodic table of elements. It helps scientists predict the properties of elements based on their position on the table and understand trends in properties such as reactivity, electronegativity, and atomic size. The arrangement of elements in the periodic table is based on their electron configurations.
By discovering the elements proton number, it became easier for scientists because the elements had similar properties. And they could arrange it by increasing proton number, valence electrons or electronic configuration.
Dmitri Mendeleev
Dmitri Mendeleev is credited with creating one of the first periodic tables that arranged elements into families based on their properties. This first version of the periodic table was organized by atomic weight and helped to predict the existence of unknown elements.
The elements are arranged in what is called the periodic table.

Mendeleev arranged the elements in the periodic table according to their atomic masses.
