Vitaly Khlopin is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Vitaly Khlopin rather than just read about it. In short: Vitaly Grigorievich Khlopin (Russian: Вита́лий Григо́рьевич Хло́пин) (January 1890 - 10 July 1950) was a Russian and Soviet radiochemist, professor, academician of the USSR Academy of Sciences (1939), Hero of Socialist Labour (1949), and director of the Radium Institute of the USSR Academy of Sciences (1939-1950).

Reference excerpt

Vitaly Grigorievich Khlopin (Russian: Вита́лий Григо́рьевич Хло́пин) (January 1890 - 10 July 1950) was a Russian and Soviet radiochemist, professor, academician of the USSR Academy of Sciences (1939), Hero of Socialist Labour (1949), and director of the Radium Institute of the USSR Academy of Sciences (1939-1950). He was one of the founders of Soviet radiochemistry and radium industry, received the first domestic radium preparations (1921), one of the founders of the Radium Institute and leading participants in the atomic project and founder of the school of Soviet radiochemists.

Biography He was born on January 14 (26), 1890 in Perm, in the family of a doctor Grigory Vitalievich Khlopin (1863-1929). From 1905 the Khlopins lived in St. Petersburg. Brief chronology of his life path:

1897 - began studying at a private men's school in Yuriev; 1908 - graduated from the 12th St. Petersburg Gymnasium; 1911 - graduated from the chemistry department of the University of Göttingen. 1911—1913 - at the St. Petersburg Clinical Institute of the Grand Duchess Helena Pavlovna he taught practical sessions on chemical methods of sanitary analyses; 1912 - graduated with a first degree diploma from the Faculty of Physics and Mathematics of St. Petersburg University in chemistry; 1912-1917 - remained at the University at the Department of General Chemistry as an assistant, where under the guidance of L. A. Chugaev he was being prepared for teaching (the first work with L. A. Chugaev on the synthesis of complex compounds of platonitrite with dithioethers); 1913-1916 - engaged in experimental research in the chemistry of platinum compounds and analysis of rare elements; 1914, 1915 - laboratory assistant at the Petrograd Central City Chemical Laboratory; 1915 - at the suggestion of Academician V.I. Vernadsky he started working in the Radiological Laboratory of the Academy of Sciences (organized in the autumn of 1911 in the former studio of A.I. Quindzhi on Vasilievsky Island) as a specialist in chemistry (until 1921); 1915, 1916 - at the suggestion of the Chemical Committee at the State Academy of Sciences, conducts experimental work on obtaining products of military-chemical importance (some asphyxiants) and on developing methods for obtaining pure platinum from Russian raw materials, and on behalf of the Central Laboratory of the Central Laboratory of the Navy Department participates in the development of a method for obtaining sodium azide; Autumn 1916 - the Military Chemical Committee sent as a specialist in chemistry as the head of sanitary and evacuation part in the "Urmiyskaya Expedition for the survey of boron-acid springs of the Kara region and the Urmiysky lake area"; 1916 - member of the Commission for the Study of the Natural Productive Forces of Russia (CNPF); 1917 - until the liquidation of the Committee for Military Labor Assistance - secretary of its Chemical Division and chairman of the Commission on Luminous Compounds; in October participated in the work of the Congress on Technical Defense of the State; assistant at the Department of General Chemistry I of Petrograd University (until 1924); 1918-1919 - in summer he was elected Commissioner of the Board formed under the NPFR for the organization of the first Radium Plant in Russia. V. G. Khlopin was entrusted with the general management of issues related to the chemical and administrative side of the case; in December he was elected as a representative of CNPF to the Council of the Radium Association; from January 1919 he was a member of the Council of the Chemical Division of the Russian Technical Society; from July 1918 to September 1919 he was a member of the Council of the Platinum Institute; 1918-1934 - member of the editorial board of the Chemical-Technical Publishing House, later transformed into the publishing house Chemteoret; 1920 - elected Professor of the Department of General Chemistry at the Ural State University (unable to travel to the Urals, he was forced to give up his position); 1921 - on December 1, V. G. Khlopin obtained the first highly active preparations of domestic radium; 1922-1934 - Head of the gas department of NPFR, - Geochemical Institute of the USSR Academy of Sciences (Leningrad);

Worked examples

Example 1 — a first encounter with Vitaly Khlopin

Start with the simplest possible case. Write down what Vitaly Khlopin claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Vitaly Khlopin before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Vitaly Khlopin ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Vitaly Khlopin

In research: Vitaly Khlopin appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Vitaly Khlopin in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Vitaly Khlopin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1890 births, 1950 deaths, Burials at Tikhvin Cemetery, so understanding it makes those chapters shorter.
In everyday life: Look for Vitaly Khlopin outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
