Its atomic number is 21 and indicated by the symbol Sc. Astatine is the rarest naturally occurring element on the Earth’s crust. Atomic Mass Number – Does it conserve in a nuclear reaction? The chemical symbol for Lanthanum is La. The chemical symbol for Rhenium is Re. It is used in houses in equipment like color television, fluorescent lamps, energy saving lamps and glasses. Naturally occurring potassium is composed of three isotopes, of which 40K is radioactive. The chemical symbol for Yttrium is Y. Yttrium is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a “rare-earth element”. It has been labelled as the 50th most abundant element on Earth, distributed widely in trace quantities in over 800 minerals. Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance. The chemical symbol for Nickel is Ni. [44], The alloy Al20Li20Mg10Sc20Ti30 is as strong as titanium, light as aluminium, and hard as ceramic.

Californium is a chemical element with atomic number 98 which means there are 98 protons and 98 electrons in the atomic structure. Carbon is the 15th most abundant element in the Earth’s crust, and the fourth most abundant element in the universe by mass after hydrogen, helium, and oxygen. The most commonly used spontaneous fission neutron source is the radioactive isotope californium-252. Promethium is one of only two such elements that are followed in the periodic table by elements with stable forms. Silver is a soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal.

"Element 21" redirects here. There are over 100 different borate minerals, but the most common are: borax, kernite, ulexite etc. Its atomic number is 21 and indicated by the symbol Sc. The chemical symbol for Rubidium is Rb. Our Website follows all legal requirements to protect your privacy. The chemical symbol for Iridium is Ir. Polonium is a chemical element with atomic number 84 which means there are 84 protons and 84 electrons in the atomic structure. It is the heaviest element that can be formed by neutron bombardment of lighter elements, and hence the last element that can be prepared in macroscopic quantities. The atomic mass is the mass of an atom.

The chemical symbol for Lithium is Li. Scandium-45 isotope is used in oil refineries. This has two beneficial effects: the precipitated Al3Sc forms smaller crystals than in other aluminium alloys,[43] and the volume of precipitate-free zones at the grain boundaries of age-hardening aluminium alloys is reduced. Scandium is a monoisotopic element and its atomic weight is determined solely by its isotope 45 Sc. Lars Fredrik Nilson and his team detected this element in the minerals euxenite and gadolinite in 1879. The chemical symbol for Molybdenum is Mo. Curium is a hard, dense, silvery metal with a relatively high melting point and boiling point for an actinide.

Since it has a high melting point and low density, it would be mainly used in the form of an alloying agent in the category of metals (lightweight) for applications of high performance and military purposes. Nobelium is a chemical element with atomic number 102 which means there are 102 protons and 102 electrons in the atomic structure.

Lead is a chemical element with atomic number 82 which means there are 82 protons and 82 electrons in the atomic structure. Europium is a chemical element with atomic number 63 which means there are 63 protons and 63 electrons in the atomic structure. The chemical symbol for Arsenic is As. [50], The first scandium-based metal-halide lamps were patented by General Electric and initially made in North America, although they are now produced in all major industrialized countries. Scandium sulfate in diluted form used to improve the germination of seeds like corn, peas and wheat. Palladium, platinum, rhodium, ruthenium, iridium and osmium form a group of elements referred to as the platinum group metals (PGMs). Major advantage of lead shield is in its compactness due to its higher density. for 1+3, enter 4. The chemical symbol for Scandium is Sc. Hafnium is a lustrous, silvery gray, tetravalent transition metal, hafnium chemically resembles zirconium and is found in many zirconium minerals. It is even less abundant than the so-called rare earths. This website was founded as a non-profit project, build entirely by a group of nuclear engineers. Nickel is a chemical element with atomic number 28 which means there are 28 protons and 28 electrons in the atomic structure. [51] Scandium triflate is a catalytic Lewis acid used in organic chemistry.[53]. Usage of scandium is increasing as is a well-suited catalyzer to polish glass.

Commercially, scandium is obtained as a by-product of uranium refining. The Commission last revised the standard atomic weight of scandium in 2013 based on the latest Atomic Mass Evaluation by IUPAP. Scandium-stabilized zirconia enjoys a growing market demand for use as a high-efficiency electrolyte in solid oxide fuel cells. Occurrence.
