Who invented modern periodic table?

Answer 1

Dmitri Mendeleev was the inventor of the old Periodic Table but Henry Moseley changed the concept of atomic weight to atomic number and thus he corrected the defects in the old periodic table and he is called as the father of Modern Periodic Table.

Henry Gwyn Jeffreys Moseley (23 November 1887 - 10 August 1915) was an English physicist. Moseley's outstanding contribution to the science of physics was the justification from physical laws of the previous empirical and chemical concept of the atomic number. This stemmed from his development of Moseley's law in X-ray spectra. Moseley's Law justified many concepts in chemistry by sorting the chemical elements of the periodic table of the elements in a quite logical order based on their physics.

Moseley's law advanced atomic physics by providing the first experimental evidence in favour of Niels Bohr's theory, aside from the hydrogen atom spectrum which the Bohr theory was designed to reproduce. That theory refined Ernest Rutherford's and Antonius van den Broek's model, which proposed that the atom contains in its nucleus a number of positive nuclear charges that is equal to its (atomic) number in the periodic table. This remains the accepted model today.

Answer 2

The first major revision of the entire periodic table was carried out by Henry Gwyn-Jeffries Moseley, an English physicist who began his research under Ernest Rutherford. In 1914, Moseley showed that each atomic nucleus could be assigned a number that was equal to the number of units of positive charge (later identified as "protons") associated with it. Once the periodic table was reorganized according to this atomic number instead of atomic weight, the few discrepancies in Mendeleev's system disappeared.

Answer 3

The modern periodic table was invented by Dmitri Mendeleev, a Russian chemist, in 1869. Mendeleev arranged the elements into a table based on their atomic masses and chemical properties, predicting the properties of undiscovered elements and leaving gaps for them.
