When Did Dmitri Mendeleev Present The Periodic Table?


Who developed the periodic table?

There are many contributors to the periodic table, still extending into the present, since elements still continue to be discovered and named. But the most notable ones are the ones that developed idea early on. These two men are Dmitri Mendeleev of Russia and Lothar Meyer of Germany; they published almost identical periodic tables in 1869, and today, both are given widespread credit for mapping out the elements that the periodic table consists of. However, Mendeleev is considered today to deserve more credit since he spread and accelerated his ideas more vigorously than Meyer, so credit for the periodic table is generally attributed to Mendeleev.

Who created the periodic table?

Russian chemist, Dmitri Mendeleev is often considered the "father" of the periodic table, however, the work of many scientists contributed to its present form.

What is the difference between the modern periodic table and Mendeleev`s periodic table?

All I know is Dmitri Mendeleev organised his by atomic mass

The current periodic table is complete as far as all naturally occuring elements go. Mendeleev's version was produced in 1871, long before we had the technology to test these. He was clever enough to leave gaps for undiscovered elements.

Mendeleevs table doesn't allow space for all the transition elements, actinides or lanthanides but it was a pretty good stab. Much better than the other atempts before him.

how was the modern periodic table developed?

who how when thanks all answers appreciated

its invention is generally credited to Russian chemist Dmitri Mendeleev in 1869. Mendeleev intended the table to illustrate recurring ("periodic") trends in the properties of the elements.

tell me , what is the merit and demerits of Mendeleev periodic table?

also tell me the difference between Mendeleev periodic table and modern periodic table.

not all elements that are now known were known during Mendeleev's lifetime

his periodic table did not adequately account for the placing of the elements now called Lanthanoids and Actinoids although he showed great foresight in leaving gaps in his periodic table for undiscovered elements and even predicted the properties of some of them
