What did Dmitri Mendeleev accomplish in 1869?
In 1869, he published the greatest of his works, Principles of Chemistry, where he formulated his famous periodic table, translated into many languages and that was a textbook for many years.
He developed the periodic table.
He proposed one of the early versions of the periodic table. Hearranged the elements in the increasing order of their increasingatomic mass and repeating properties.
Dmitri Mendeleev proposed one of the early versions of the periodictable. He also arranged the elements in the increasing order oftheir increasing atomic mass and repeating pr…operties.
On March 6, 1869, Mendeleev made a formal presentation to the Russian Chemical Society, entitled The Dependence between the Properties of the Atomic Weights of the Elements, w…hich described elements according to both weight and valence. _________________________________________________________________________ In1869, Mendeleev published the first periodic table. Within 16 years, chemists discovered the three missing elements scandium, gallium, and germanium. Their properties are close to those that Mendeleev had predicted.Over all he discovered the three new or missing elements.
In 1869, a total of 63 elements had been discovered by. A few were gases. Two were liquids. Most were solid metals.
in 1869, Dmitri Mendeleev discovered a set of patterns that applyed to the elements. in that year, he also published his periodic table.
Dmitri Ivanovich Mendeleev was a Russian chemist and inventor. He formulated the PeriodicLaw, created his own version of the periodic table of elements , and used it to c…orrect theproperties of some already discovered elements and also to predictthe properties of elements yet to be discovered.
Dmitry Mendeleyev was born in Tobolsk, Siberia (in Russia), which is now Tyumen, Oblast.
Mendeleev is considered as the developer of the first periodic table. He arranged the elements in the increasing order of their atomic masses. . Mendeleev's Periodic Law sta…tes that properties of elements are the periodic functions of their atomic masses.. Mendeleev was able to predict the existence of more elements in nature and laid gaps in the periodic table for the elements to be discovered in future. Note: Mendeleev's periodic table was not free of errors. Now we follow the Bohr Periodic table. It was developed by Rang (1893), modified and developed by Warner (1905) and further developed by Bury (1921).
i was a bboy Felix
he traind to be a fire man so he could train with cemicals so he could what propoteas thay containd!
he was the man behind the discovery of periodic table according tothe atomic numbers
Dmitri Mendeleev created the first periodic table. Using his table, he was able to predict the properties of undiscovered elements.
He showed us how we can arrange the elements. This actually helpesus find out if we are missing any elements or if there are unkownelements. Without this guy, it wud be reall…y hard to understand elements inchemistry.
Dimitri Mendeleev developed the law of periods and the periodic table, and described the properties of several elements before they were isolated by scientists.
