How is the modern periodic table different from Dmitri mendeleev's table?

The only important difference is that the modern periodic law must be framed in terms of atomic numbers, where Mendeleev framed the original periodic law in terms of atomic weights.
There are only three places where this makes a difference. For cobalt and nickel Mendeleev assigned both exactly the same atomic weight -- well within the error margins at the time. For tellurium and iodine, Mendeleev insisted, wrongly, that the recognised atomic weight of tellurium was wrong, and that it had to be less than that of iodine. And the third case did not come up until later, because argon was not discovered until 1894 (element number 18, argon, has an atomic weight greater than that of element 19, potassium).

Who is credited with the modern periodic table?
The modern long form of periodic table was constructed by Dmitri Mendeleev (1869).
Who developed your modern periodic table in 1869?
Dmitri Mendeleev developed the modern periodic table in 1869.
Who introduced the name periodic table?
It was named by Russian chemist Dmitri Mendeleev in 1869, in memory of his then recently-deceased colleague and clandestine "gentleman friend", Benjamin D. Periodic.
The discovery of a periodic table closest to its modern form was the result of which scientist's work with decks of cards?
Dmitri MendeleevDmitri MendeleevDmitri Mendeleev is the scientists that worked with decks of cards to decelop the arrangement of elements on the periodic table in the 1860's.
Scientist that first arranged and classfied elements into a chart?
Dmitri Mendeleev is credited with being the first scientist to arrange and classify elements into a chart. He was a Russian chemist who lived from 1834 to 1907.
Who is mendeleevs?
Dmitri Mendeleev was a Russian chemist; he proposed the modern Periodic Table of elements in 1869.

Dmitri Mendeleev developed the modern periodic table in 1869.
Who is dmitri mendelev?
Dmitri Mendelev was a Russian scientist who created the first modern periodic table of elements.
Who came up with periodic table?
Dmitri Mendeleev came up with the modern Periodic Table in 1869.

What scientist published the modern periodic table how was this arranged?
This chemist was Dmitri Mendeleev in 1869; the arrangement is based on the law of periodicity.
Who is the inventor of the periodic table?
Dmitri Mendeleev is generally credited, as he was able to predict the properties of elements which had not yet been discovered based on 'gaps' in his table. He ordered the known elements in terms of their atomic mass in 1869; elements are listed in order of increasing atomic number in the modern version.
Which scientist did periodic table of elements?
Dmitri Mendeleev developed the first periodic table. But the modern table was developed by Henry Moseley.
