Scandium properties

Scandium is a silver-white metal which develops a slightly yellowish or pinkish cast upon exposure to air. A relatively soft element, scandium resembles yttrium and the rare-earth metals more than it resembles aluminum or titanium Scandium, dendritic pieces, purified by distillation, 99.9% trace rare earth metals basis Scandium, foil, not light tested, 25x25mm, thickness 0.0125mm, as rolled, 99% Scandium, foil, not light tested, 25x25mm, thickness 0.025mm, as rolled, 99% Scandium, powder, max. particle size 250 micron, weight 1 g, purity 99.9 Properties of Scandium The metal has a silvery-white appearance while having a moderately soft texture. Owing to the formation of Sc 2 O 3 oxide on its surface, its stability in air changes slowly to a yellowish form

The properties of scandium compounds are intermediate between those of aluminium and yttrium. A diagonal relationship exists between the behavior of magnesium and scandium, just as there is between beryllium and aluminium. In the chemical compounds of the elements in group 3, the predominant oxidation state is +3 Scandium is a soft, silvery transition element which occurs in rare minerals from Scandinavia. It develops a slightly yellowish or pinkish cast when exposed to air. Scandium tarnished in air and burn easily, once it has been ignited. It reacts with water to form hydrogen gas and will dissolve in many acids

Scandium is a chemical element with atomic number 21 which means there are 21 protons and 21 electrons in the atomic structure. The chemical symbol for Scandium is Sc. Scandium is a silvery-white metallic d-block element, it has historically been sometimes classified as a rare-earth element, together with yttrium and the lanthanides Scandium is a chemical element with atomic number 21 which means there are 21 protons and 21 electrons in the atomic structure Thermal conductivity of Scandium is 15.8 W/ (m·K). The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K. It is a measure of a substance's ability to transfer heat through a material by conduction

Physical properties of Scandium include melting point, boiling point, mechanical strengt It is well known that small quantities of scandium, a rare earth metal, added to aluminium alloys significantly improve the tensile strength and physical properties of the finished product Scandium is a silvery-white metallic d-block element, it has historically been sometimes classified as a rare-earth element, together with yttrium and the lanthanides Scandium is a silvery white, moderately soft metal. It is fairly stable in air but will slowly change its colour from silvery white to a yellowish appearance because of formation of Sc 2 O 3 oxide on the surface Properties of this type of metal, among which is scandium, are its high hardness, having high boiling and melting points and being good conductors of electricity and heat. The state of the scandium in its natural form is solid. Scandium is a silver white chemical element and belongs to the group of transition metals

Scandium is a silvery-white metallic transition metal, often classified as a rare earth element (REE), together with yttrium (Y) and the 15 lanthanides (La) Scandium is a soft, light, silvery-white metal, which becomes slightly tinged with yellow or pink when exposured to air. Scandium is almost as light (low density) as aluminum but it has a much higher melting point Properties and Trends in Transition Metals. The elements of the second and third rows of the Periodic Table show gradual changes in properties across the table from left to right as expected. Electrons in the outer shells of the atoms of these elements have little shielding effects resulting in an increase in effective nuclear charge due to the addition of protons in the nucleus Scandium in Periodic Table. Scandium (Sc), chemical element or rare-earth metal of Group 3 of the periodic table has only one common oxidation number or state +3 with no d-electron.Scandium is a silvery-white, moderately soft metal that usually occurs with the lanthanides due to the lack of the characteristics of transition elements Scandium is a silvery-white transition metal located in group 3 of the periodic table.
