Saint Petersburg State UniversitySaint Petersburg State University (SPbU; Russian: Санкт-Петербургский государственный университет, romanized: Sankt-Peterburgskiy gosudarstvennyy universitet) is a publicresearch university in Saint Petersburg, Russia. Founded in 1724 by a decree of Peter the Great, it is one of the oldest universities in Russia and has had a focus on fundamental research in science and engineering since its creation.
Saint PetersburgSaint Petersburg, formerly known as Petrograd (Петроград), and later Leningrad (Ленинград), is the second-largest city in Russia, after Moscow, the nation's capital. Situated on the Neva River at the head of the Gulf of Finland on the Baltic Sea, its area of 1,439 square kilometers (556 sq mi) makes it the smallest administrative division of Russia by area.
Periodic tableTabular arrangement of the chemical elementsPeriodic table of the chemical elements showing the most or more commonly named sets of elements (in periodic tables), and a traditional dividing line between metals and nonmetals.
Periodic trendsIn chemistry, periodic trends are specific patterns present in the periodic table that illustrate different aspects of certain elements when grouped by period and/or group. They were discovered by the Russian chemist Dmitri Mendeleev in 1863. Major periodic trends include atomic radius, ionization energy, electron affinity, electronegativity, nucleophilicity, electrophilicity, valency, nuclear charge, and metallic character.
Russian Orthodox ChurchAutocephalous Eastern Orthodox churchThe Russian Orthodox Church (ROC; Russian: Русская православная церковь, РПЦ, romanized: Russkaya pravoslavnaya tserkov', RPTs;), also officially known as the Moscow Patriarchate (Russian: Московский патриархат, romanized: Moskovskiy patriarkhat), is an autocephalousEastern Orthodox Christian church. It has 194 dioceses inside Russia.
ChemistA chemist (from Greek chēm(ía) alchemy; replacing chymist from Medieval Latinalchemist) is a graduated scientist trained in the study of chemistry, or an officially enrolled student in the field. Chemists study the composition of matter and its properties. Chemists carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms.

GermaniumGermanium is a chemical element; it has the symbol Ge and atomic number 32. It is lustrous, hard-brittle, grayish-white and similar in appearance to silicon. It is a metalloid (sometimes considered a nonmetal) in the carbon group that is chemically similar to silicon. Like silicon, germanium naturally reacts and forms complexes with oxygen in nature. Because it seldom appears in high concentration, germanium was found comparatively late in the discovery of the elements.
Synthetic elementA synthetic element is a known chemical element that does not occur naturally on Earth: it has been created by human manipulation of fundamental particles in a nuclear reactor, a particle accelerator, or the explosion of an atomic bomb; thus, it is called "synthetic", "artificial", or "man-made". The synthetic elements are those with atomic numbers 95–118, as shown in purple on the accompanying periodic table: these 24 elements were first created between 1944 and 2010.
ScandiumScandium is a chemical element; it has symbol Sc and atomic number 21. It is a silvery-white metallic element found in the d-block of the periodic table. Usually, it is classified as a rare-earth element, together with yttrium and the lanthanides. It was discovered in 1879 by spectral analysis of the minerals euxenite and gadolinite from Scandinavia.
