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.
Dmitri Mendeleev
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.
The scientist who recognized the periodic table for atomic number was Henry Moseley. He discovered that elements should be ordered by atomic number rather than atomic mass, which led to the modern understanding of the periodic table.
The periodic table was first proposed by a Russian chemist Dimitri Mendeleev. The modern periodic table ordered by atomic number was proposed by an English physicist, Henry Moseley.
Dmitri Mendeleev created the first periodic table according to atomic mass
it’s false
He could not because it had not yet been discovered when he created the table. However he was able to determine that an element was missing at that location and predict the properties it would have when it was discovered. When germanium was discovered and named, his predictions were found to be very accurate.
