Allotropes The three most common basic crystal patterns are: This website was founded as a non-profit project, build entirely by a group of nuclear engineers. It reacts with water to form hydrogen gas and will dissolve in many acids, but It is not attacked by a 1:1 mixture of HNO3 and 48% HF. and Gay-Lussac, L.-J. It is given by the ratio of the shear stress to the shear strain. Scandium has an abundance in the Earth's crust of 22 mg/kg (or parts per million). Required fields are marked *, Scandium Sc (Element 21) of Periodic Table, When finely divided (powdered form) or heated, It dissolves in, It has great potential (having or showing the capacity) because it has almost as low a density as, Uses of scandium are still growing, because of it is suited to produce, But there have been suggestions that some of its compounds might be, Only trace amounts of element reach the food chain, so the average humans daily intake is less than, The metal is widely distributed on earth, it occurs in very minute quantities in over, Scandium is the main component of the very rare mineral, It is also found in the residues (a small amount of something that remains after the main part has gone) remaining after the extraction of tungsten from, It is extracted as a by-product from uranium mill, World’s Top 3 Reserve holders of Scandium, International Baccalaureate IB Chemistry (SL) Past Papers, International Baccalaureate IB Chemistry (HL) Past Papers, International Baccalaureate IB Physics (HL) Past Papers. 4×10-6% (In Sun) It is extracted as a by-product from uranium mill tailings (the residue of something). Each allotrope has different physical properties. Visualize trends, 3D orbitals, isotopes, and mix compounds. This is approximately the sum of the number of protons and neutrons in the nucleus. Scandium, atomic number 21. Crystal structure:  Hexagonal close packed Scandium can be recovered from thortveitite or extracted as a by-product from uranium mill tailings (sandy waste material). Values are given for typical oxidation number and coordination. The advent of new frame materials, such as carbon fibre and titanium, has somewhat lessened the popularity of scandium alloy bike frames, but many such frames are still being made today. Based upon that oxidation number, an electronic configuration is also given but note that for more exotic compounds you should view this as a guide only. The temperature at which the solid–liquid phase change occurs. Pure (99.998) Sublimed Dendritic Scandium, Identity A quarry near the village of Ytterby yielded two different mineral ores, from which the seventeen so-called "rare earth" elements were eventually identified, those being scandium, yttrium and the fifteen lanthanide elements. Scandium is mainly used for research purposes. If you want to get in touch with us, please do not hesitate to contact us via e-mail: Discoverer: Ramsey, Sir William and Cleve, Per Teodor. CAS Number: CAS7440-20-2 The number of protons in an atom. The atomic number of each element increases by one, reading from left to right.

Members of a group typically have similar properties and electron configurations in their outer shell. For example, it wasn't until the 1960s when the first pound, or 450 grams, of high purity scandium was obtained. The number of atoms of the element per 1 million atoms of the Earth’s crust. Vaporization heat:  332.7 kJ/mol Scandium is a silver-white metal which develops a slightly yellowish or pinkish cast upon exposure to air. Prairie Dogs: A Threatened Species or Public Health Nuisance? A list of reference sources used to compile the data provided on our periodic table of elements can be found on the main periodic table page. 2 Sc (s) + 6 HCL (aq) → 2 Sc3+ (aq) + 6 Cl– (aq) + 3 H2 (g), The Scandium oxide (Sc2O3) and hydroxide (Sc(OH)6) are amphoteric: One which helped demonstrate the power of the periodic table, and which you'll find illuminating football fields, and in the frames of mountain bikes. 2) CIS Countries (inc.

The radioactive isotope 46Sc is used as a tracing agent in refinery crackers for crude oil, etc. The images may not be posted on any website, shared in any disc library, image storage mechanism, network system or similar arrangement. It has 21 protons and 21 electrons in the atomic structure. Data for this section been provided by the British Geological Survey. A vertical column in the periodic table. Lattice constant:  330.9, 330.9, 526.8 pm ". If you continue to use this site we will assume that you are happy with it. Scandium - Periodic Table. So, that's Scandium - the element first found in the late eighteenth century, and not isolated pure and in large quantities until the middle of the twentieth century. In addition technical terms are linked to their definitions and the menu contains links to related articles that are a great aid in one's studies. It has, however, great potential because it has almost as low a density as aluminium and a much higher melting point. The SI unit of electrical resistivity is the ohm-metre (Ω⋅m). Values are given for typical oxidation number and coordination. Electrical resistance is expressed in Ohms. The transition of a substance directly from the solid to the gas phase without passing through a liquid phase. Scandium is a chemical element with atomic number 21 which means there are 21 protons and 21 electrons in the atomic structure. The role of the element in humans, animals and plants. The blue color of beryl (aquamarine variety) is said to be due to scandium. Periodic Table of Elements - Scandium - Sc. This is approximately the sum of the number of protons and neutrons in the nucleus. DOT Number:  3089, Pronunciation:  Skan-dee-am The sum of the oxidation states within a compound or ion must equal the overall charge. Scandium is a 21. chemical element in the periodic table of elements. Quantum Number:  2D3/2 The oxidation state of an atom is a measure of the degree of oxidation of an atom. One which helped demonstrate the power of the periodic table, and which you'll find illuminating football fields, and in the frames of mountain bikes.
