Elements are first organized by atomic number (left to right, top to bottom). They are organized into columns by their properties. The properties of an element are directly related to how many valence electrons that element has, so, with the exception of Helium, all of the elements in a column have the same number of valence electrons.
By grouping the elements on the Periodic Table.
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.
Atomic number was not used by Mendeleev to organize his periodic table. He organized the elements based on their atomic mass and properties, leaving gaps for undiscovered elements that were later filled.
Chemists organized the elements by properties, specifically by atomic mass, to create the periodic table. This organization allowed them to identify patterns and trends among elements based on their chemical behavior. The periodic table was further refined over time as new elements were discovered and their properties were better understood.
Periods in the periodic table are horizontal rows that categorize elements based on the number of electron shells they have. Each period represents a new energy level for the elements. The periods help organize the elements by grouping together those with similar properties and characteristics.

The periodic table organizes the elements by atomic number (number of nuclear protons).
To organize the elementsTo organize various elements so that it is easy to study the various elements.
Dmitiri Mendeleev arranged the Periodic Table of elements in order of increasing atomic masses.

In order to organize the elements
Some people have suggested that Dmitri Mendeleev did first organize elements in a periodic table in a dream.

Mendeleev from Russia was the first person to organize the periodic table of the elements
