It is helpful to organize things by characteristics because you can tell that certain elements are similar. For example if you knew nothing about the chemical or physical properties of (Rb) Rubidium, you could guess it has properties similar to (Cs) Cesium since they are in the same group. The common "Periodic Table" has many interesting forms. Search: "periodic table"
Dmitri Mendeleev is credited with publishing the first version of the periodic table in 1869. He arranged the elements based on their atomic weight and properties, creating a table that predicted the properties of missing elements.
The periodic table lists elements according to their atomic number, which is the number of protons in the nucleus of an atom of that element. Elements are arranged in order of increasing atomic number from left to right and top to bottom.
Elements are organized in the periodic table by their atomic number, which represents the number of protons in the nucleus of an atom. The atomic number determines the unique properties of each element, and elements with similar properties are grouped together in columns called groups.

In order to organize the elements
Some people have suggested that Dmitri Mendeleev did first organize elements in a periodic table in a dream.
A period on the periodic table is a horizontal row of elements that share similar properties. It helps organize the elements by arranging them in order of increasing atomic number and grouping elements with similar chemical properties together.
Mendeleev from Russia was the first person to organize the periodic table of the elements
