Dmitri Ivanovich Mendeleev [b] (/ ˌ m ɛ n d əl ˈ eɪ ə f / MEN-dəl-AY-əf; [2] [c] [a] 8 February [O.S. 27 January] 1834 – 2 February [O.S. 20 January] 1907) was a Russian chemist known for formulating the periodic law and creating a version of the periodic table of elements.

2025年2月12日 · Dmitri Mendeleev, Russian chemist who devised the periodic table of the elements. Mendeleev found that, when all the known chemical elements were arranged in order of increasing atomic weight, the resulting table displayed a recurring pattern, or periodicity, of properties within groups of elements.

2014年4月2日 · Russian chemist Dmitri Mendeleyev discovered the periodic law and created the periodic table of elements. (1834-1907) Who Was Dmitri Mendeleyev? After receiving an …

Mendeleev’s wish led to his discovery of the periodic law and his creation of the periodic table – one of the most iconic symbols in science: almost everyone recognizes it instantly: science has few other creations as well-known as the periodic table.

2023年3月8日 · Dmitri Mendeleev ‘s periodic table is the forerunner to the modern periodic table. It is a “ periodic ” table because it groups elements in rows and columns that showcase recurring properties, such as valence, electronegativity, and ionization energy.

2019年5月15日 · Dmitri Mendeleev (February 8, 1834–February 2, 1907) was a Russian scientist best known for devising the modern periodic table of elements. Mendeleev also made major contributions to other areas of chemistry, metrology (the …

2007年4月12日 · Mendeleev’s greatest achievement was not the periodic table so much as the recognition of the periodic system on which it was based. This year marks the 100th anniversary of the death of one of the most famous scientists of all time, the Russian chemist Dmitri Ivanovich Mendeleev (1834–1907).

Dmitri Mendeleev, Mendeleyev also spelled Dmitry Mendeleyev, (born Feb. 8, 1834, Tobolsk, Siberia, Russia—died Feb. 2, 1907, St. Petersburg), Russian chemist. He was a professor of chemistry at the University of St. Petersburg (1867–90) and later served as director of Russia’s bureau of weights and measures.

Mendeleev made an early periodic table. In the modern periodic table, elements are in order of atomic number in periods and groups. Electronic configurations model how electrons are arranged in...

2025年2月12日 · Dmitri Mendeleev - Periodic Table, Chemistry, Elements: Since Mendeleev is best known today as the discoverer of the periodic law, his chemical career is often viewed as a long process of maturation of his main discovery.
