Yes, Dmitry Mendeleev is credited with developing the first version of the periodic table in 1869. He organized the elements based on their atomic mass and properties, and left gaps for elements that had not yet been discovered.
No,its not Dmitri Mendeleev.Dmitri Mendeleev create the first periodic table but mostly it was wrong....he arranged them by the atomic number when it should have been by increasing the atomic number(and ya there's a difference)..the one that rearranged it was Henry Moseley.
Henry Mosley
Henry Moseley updated the periodic table in 1913 by arranging elements by atomic number instead of atomic mass. His work reorganized the elements and corrected inconsistencies in the periodic table.
Mosley arranged elements in order of increasing atomic number
Dmitri Mendeleev created and sorted the periodic table by atomic mass. When years later Mosley rearranged the table and sorted it by Atomic number.
There have been two make ups of the periodic table so far Mosley made the first one but was overtaken by Dimitri Mendeleev's form, which we use today.

Dimitri Ivanovich Mendeleev was the one who first created the periodic table of elements.After that, Henry Mosley modified it on the basis of atomic number,
Mendeleev used atomic masses to classify the element, where as Moseley classified the element in terms of atomic number, he suggested that chemical and physical properties are the functions of the atomic number Elements in the periodic table is classified as Metals, Nonmetal and Metalloids. Normally Group 1 to 12 are metals... Sayed Abdul Aziem Sayed_abd2007@hotmail.com
The first slightly inaccurate Periodic Table of Elements was invented in the mid 1800's. Then Henry Mosley found the mistakes and re-corrected them in the early 1900's, which now is our current periodic table that we use.
Mendeleev's Periodic Table was different from Moseley's in that Mendeleev arranged the elements inÊthe table according to atomic masses while Mosley's periodic table was arranged accordingÊto atomic numbers that were increasing.ÊÊThe modern periodic table used today is based on the Moseley model.

Dmitri Mendeleev is credited with creating the first version of the periodic table in 1869. Mendeleev arranged the elements by atomic mass and predicted the properties of undiscovered elements. Subsequent scientists, such as Henry Moseley, contributed to refining and organizing the periodic table based on atomic number.
MOSLEY
They really didn't they thought of a theory of everything being made up of atoms. Such as Mendeleev and Mosley
