Dmitri Mendeleev
The periodic law states that a large number of the physical and chemical properties of elements recur systematically. This is why the periodic table is arranged as it is, to reflect this pattern.
Properties of elements are a periodic function of their atomic masses.
not known. although it is assumed to be discovered during the 10th century.
Gallium, discovered in 1875 by French chemist Paul-Émile Lecoq de Boisbaudran, was significant because it was the first element predicted by Mendeleev's periodic table before its discovery. Its existence confirmed the validity of the periodic law and the predictive power of the periodic table. Additionally, gallium's unique properties, such as its low melting point and ability to remain liquid just above room temperature, have led to various applications in electronics and thermometers.

Moseley discovered the modern periodic table.
Dmitri Mendeleev was the Russian scientist who discovered the periodic law and created the first version of the periodic table in 1869. He arranged the known elements by their atomic mass, demonstrating a periodic arrangement of properties that revealed recurring patterns.
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.
Demitri Mendeleev discovered a pattern to the periodic table in 1869.
The modern periodic law states that, The properties of the elements are the periodic function of there atomic number not atomic weights.
1869
Dmitri Mendeleev, a Russian chemist, discovered the periodic law and created the periodic table of elements in 1869. Mendeleev's table arranged elements based on their atomic mass and predicted the existence and properties of undiscovered elements.
Moseley discovered modern periodic table. It was not given by Bohr.
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.
