modern periodic law
The principle you're referring to is the Periodic Law. It states that the properties of elements are periodic functions of their atomic number, which is why the elements are arranged in a periodic manner in the periodic table. This organization helps identify trends and similarities in the properties of elements based on their atomic structure.
The modern periodic law states that, The properties of the elements are the periodic function of there atomic number not atomic weights.
The pattern of repeating properties of elements in the periodic table is called periodicity. This periodicity arises from the similar electronic structure and arrangements of elements within the table.

The periodic law is a law that states that the repeating chemical and physical properties of elements change periodically.
This statement is a fundamental principle of the periodic law, proposed by Dmitri Mendeleev. The periodic law states that when elements are arranged by increasing atomic number, there will be a periodic repetition of their properties.
Dimitri Mendeleev developed the law of periods and the periodic table, and described the properties of several elements before they were isolated by scientists.
An element's atomic number is equal to the amount of electrons or protons in an atom of that element. When an atomic number increases or decreases, the amount of electrons is changing.
The periodic law proposed by Dmitri Mendeleev states that the properties of elements are periodic functions of their atomic weights. Mendeleev used this law to create the first periodic table of elements, predicting the properties of missing elements and organizing them based on their atomic weights and chemical properties.
Dmitri Mendeleev was a Russian scientist who is credited with creating the periodic table of elements in 1869. He arranged the elements in order of increasing atomic mass and noticed patterns in their properties which led to the periodic law. Mendeleev's work laid the foundation for modern chemistry.
