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.

Dmitri Ivanovich Mendeleev[b] (/ ˌmɛndəlˈeɪəf / 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.

Mendeleev discovered the periodic table (or Periodic System, as he called it) while attempting to organise the elements in February of 1869. He did so by writing the properties of the elements on pieces of card and arranging and rearranging them until he realised that, by putting them in order of increasing atomic weight, certain types of ...

2024年9月1日 · Moseley’s Periodic table was developed by Henry Gwyn Jeffreys Moseley in the year 1914. During his time, the atomic structure was known, so he had a clear idea about the protons, neutrons and electrons.

Mendeleev created the first periodic table and was shortly followed by Meyer. They both arranged the elements by their mass and proposed that certain properties periodically reoccur. Meyer formed his periodic law based on the atomic volume or molar volume, which is the atomic mass divided by the density in solid form.

2019年1月2日 · In the autumn of 1856 Mendeleev successfully defended a master’s thesis on relationships between the specific volumes of substances and their crystallographic and chemical properties. Shortly afterwards the University of St Petersburg licensed him as a chemistry tutor, allowing him access to its laboratory.

2007年2月28日 · Russia's most famous chemist and formulator of the Periodic Table, died 100 years ago. In this article, the first of two to celebrate the legacy of Dmitri Mendeleev, we look at his life and work.

2024年4月23日 · Mendeleev, who first published his periodic table in 1869 (Figure \(\PageIndex{1}\) ), is usually credited with the origin of the modern periodic table. The key difference between his arrangement of the elements, and that of Meyer and others, is that Mendeleev did not assume that all the elements had been discovered (in fact, only about two ...
