The atomic mass is carried by the atomic nucleus, which occupies only about 10-12 of the total volume of the atom or less, but it contains all the positive charge and at least 99.95% of the total mass of the atom. The chemical symbol for Gadolinium is Gd. In 1779 Peter Woulfe examined the mineral now known as wolframite and concluded it must contain a new substance. Thulium is the thirteenth and third-last element in the lanthanide series. Elemental rubidium is highly reactive, with properties similar to those of other alkali metals, including rapid oxidation in air. The name Tungsten comes from the Swedish words tung sten, which mean "heavy stone." In nuclear industry, especially natural and artificial samarium 149 has an important impact on the operation of a nuclear reactor. The chemical symbol for Tungsten is W. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. Tungsten is a chemical element with atomic number 74 which means there are 74 protons in its nucleus. The standard SI unit is kilograms per cubic meter (kg/m3). Therefore, we cannot determine the neutron number of uranium, for example.

The chemical symbol for Nobelium is No. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name, kohl. The chemical symbol for Lutetium is Lu. Boiling point of Tungsten in Kelvin is 5828 K. Tungsten melting point is 3407 °C. Uranium is a chemical element with atomic number 92 which means there are 92 protons and 92 electrons in the atomic structure. Thorium is commonly found in monazite sands (rare earth metals containing phosphate mineral). Only about 5×10−8% of all matter in the universe is europium. The chemical symbol for Titanium is Ti. Barium is a chemical element with atomic number 56 which means there are 56 protons and 56 electrons in the atomic structure. Niobium is a soft, grey, ductile transition metal, often found in the minerals pyrochlore (the main commercial source for niobium) and columbite. The chemical symbol for Barium is Ba. The chemical symbol for Erbium is Er. The chemical symbol for Boron is B. Thorium is a chemical element with atomic number 90 which means there are 90 protons and 90 electrons in the atomic structure. Manganese is a metal with important industrial metal alloy uses, particularly in stainless steels. The chemical symbol for Berkelium is Bk. The chemical symbol for Samarium is Sm. It is an extremely reactive element and a strong oxidising agent: among the elements, it has the highest electron affinity and the third-highest electronegativity, behind only oxygen and fluorine. Its atomic number is 74 and is indicated by the symbol W. In the periodic table, it is member of d-block, 6 th group and 6 th period. Gold is thought to have been produced in supernova nucleosynthesis, from the collision of neutron stars. Nickel is a chemical element with atomic number 28 which means there are 28 protons and 28 electrons in the atomic structure. All isotopes of radium are highly radioactive, with the most stable isotope being radium-226. Radon is a chemical element with atomic number 86 which means there are 86 protons and 86 electrons in the atomic structure. Argon is mostly used as an inert shielding gas in welding and other high-temperature industrial processes where ordinarily unreactive substances become reactive; for example, an argon atmosphere is used in graphite electric furnaces to prevent the graphite from burning. Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. Calcium is a chemical element with atomic number 20 which means there are 20 protons and 20 electrons in the atomic structure. Caesium is a soft, silvery-gold alkali metal with a melting point of 28.5 °C, which makes it one of only five elemental metals that are liquid at or near room temperature.
