You can mainly blame the Russian chemist Dmitri Mendeleyev (or Mendeleev, or Mendeleyef - there are many different spellings of his name.)
Back in the early 19th century, a German chemist named Johann Dobereiner noticed that some of the elements fitted naturally into groups of three, called triads, with similar chemical and physical properties. The English chemist John Newlands was the first to notice that if you arranged the elements in order of Atomic Mass, they seemed to have similar physical and chemical properties every eight elements. He called this the law of octaves, because the way in which these properties repeated every eight elements was similar to the way the same note was repeated every eight notes (octave) on a piano. However, at times his scheme broke down, and he realised there was something wrong with it, abandoning the octave idea. His fellow chemists mocked him for it - someone once said he'd have better luck listing the elements in alphabetical order and looking for patterns!
It was Mendeleyev who in 1859 took Newlands' idea of looking for repeated properuties in the elements, and decided to create a table of elements in increasing atomic mass. Unlike Newlands, he left gaps where the pattern did not fit, and predicted new elements would be discovered, predicting their properties from the table. These elements were subsequently discovered, and since then, Mendeleyev's periodic table has been the most useful chart in chemistry.

Arsenic did not create the first periodic table. The first periodic table was created by Dmitri Mendeleev, a Russian chemist, in the 1860s. Other scientists had organized elements in other ways prior to the invention of Mendeleev's periodic table, but the other methods were criticized and did not catch on.

MD stands for a Mendelevium, which is a synthetic element with the atomic number 101 on the periodic table. It belongs to the actinide series and is named after Dmitri Mendeleev, the scientist who first proposed the periodic table.
Mendeleev developed the first periodic table and Mosely later modernized it.
Jack Black
The credits of doing that are on Mendeleev's account, a Russian scientist.
No, Dmitri Mendeleev in Russia developed the first periodic table.
Dmitri Mendeleev created the first periodic table according to atomic mass
he developed the first periodic table in the increasing order of atomic masses of elements.but after the discovery of isotopesthis periodic table was not consider to be effective.
MOSLEY
Dmitri Mendeleev was the first scientist to create the periodic table
Dmitri Mendeleev in 1869
The initial development of the Periodic Table was attriibuted to Russian scientist, Dmitri Mendeleev.The first Periodic Table was published by Mendeleev in1869 and comprised 63 elements, arranged by their atomic masses and according to the increasing number of protons in their nucleus.
Dmitri Mendeleev is credited with developing the periodic table of elements in 1869. He arranged the elements by increasing atomic mass, grouping together elements with similar properties. Mendeleev's table formed the basis for the modern periodic table.
Moseley discovered the modern periodic table.
