Scandium in a sentence

The main application of scandium by weight is in aluminium-scandium alloys for minor aerospace industry components.

This material adopts a sheet-like structure that exhibits extensive bonding between the scandium(II) centers. citation Scandium hydride is not well understood, although it appears not to be a saline hydride of Sc(II).

Significant anomalies of Scandium and Cobalt have been identified in the Buriti Zone, adding additional potential resource value to the project.

Imperial has secured several important introductions to consumers and manufacturers of products and alloy materials that utilize scandium.

As is observed for most elements, a diatomic scandium hydride has been observed spectroscopically at high temperatures in the gas phase.

As well as the elements of groups 4 to 11, they add scandium and yttrium in group 3 which have a partially filled d subshell in the metallic state.

Despite this low level of use, scandium offers significant benefits.

Groups 3–10 have no trivial names and are referred to simply by their group numbers or by the name of the first member of their group (such as "the scandium group" for Group 3 ), since they display fewer similarities and/or vertical trends.

However, this position has sometimes been disputed, on the grounds that yttrium and to a lesser extent scandium are closer in their chemical properties to lutetium than lanthanum.

In all four halides, the scandium is 6-coordinated.

In part because of this similarity, scandium is often classified as a lanthanide-like element.

Organic derivatives main Scandium forms a series of organometallic compounds with cyclopentadienyl ligands (Cp), similar to the behavior of the lanthanides.

Position in the periodic table Traditionally, from the 1940s, lanthanum has been placed under scandium and yttrium in group 3 of the periodic table, as its differentiating electron from the previous element goes into a d-orbital.

Properties Chemical characteristics of the element Scandium is a soft metal with a silvery appearance.

Scandium is present in most of the deposits of rare earth and uranium compounds, but it is extracted from these ores in only a few mines worldwide.

See, for example: citation Early techniques for chemically separating scandium, yttrium and lutetium relied on the fact that these elements occurred together in the so-called "yttrium group" whereas La and Ac occurred together in the "cerium group".

The controversy over which two elements occupy the Group 3 positions below scandium and yttrium is further discussed in the Open questions and controversies section of this article.

The positive effects of scandium on aluminium alloys were discovered in the 1970s, and its use in such alloys remains its only major application.

The primary decay products before 48 Ti are element 21 ( scandium ) isotopes and the primary products after are element 23 ( vanadium ) isotopes.
