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.
The modern periodic table was invented by Dmitri Mendeleev in 1869. Mendeleev organized the elements by increasing atomic mass and grouped them based on similar chemical properties, which laid the foundation for the periodic table we use today.
Mendeleev invented the periodic table.
Periodic table of elements.
Yes.The modern periodic table is organized by atomic number. The elements properties are found to be periodic.
Dmitri invented a periodic table in 1869 where he arranged the elements in order of increasing atomic masses.

The Periodic Table Of Elements Was Invented iN 1869, By A Russian Chemist Named Dmitri Mendeleev.
It was invented in russia by Dmitri Mendeleevhe Periodic Table was invented and arranged by the Russian chemist Dmitri Mendeleev (1834-1907).
7 periods and 18 groups are there on the modern periodic table.

The modern long form of periodic table was constructed by Neils Bohr based on modern periodic law proposed by Moseley.
