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.
The element Scandium was discovered by F. Nilson in year 1879 in Sweden. Scandium was first isolated by F. Nilson in 1879. Scandium derived its name from Scandia, the Latin name for Scandinavia. Nilson split Marignac's ytterbia into pure ytterbia and a new element that matched Mendeleev's 1871 predicted eka-boron.

Scandium exists in the + 3 oxidation state as Sc(OH) 3 in seawater. Dissolved scandium has a quasi-linear vertical profile (Fig. 4), with low concentrations at the surface and enrichment at depth, yet little interocean fractionation is observed.In the northeast Pacific, dissolved scandium is 7–11 pmol kg − 1 in the surface water and 18–22 pmol kg − 1 in deep waters.

Scandium-44 (44 Sc) is a radioactive isotope of scandium that decays by positron emission to stable 44 Ca with a half-life of 4.042 hours.. 44 Sc can be obtained as a daughter radionuclide of long-lived 44 Ti (t 1/2 60.4 a) from 44 Ti / 44 Sc generator or can be produced by nuclear reaction 44 Ca ( p, n) 44 Sc in small cyclotrons. This isotope is of potential interest for clinical PET …
Scandium is an element with the atomic number 21 and represented with the symbol ' Sc ' in the periodic table. Scandium is mined from one of the rare minerals from Scandinavia. The colour it develops when exposed to air is yellowish or pinkish cast. One of the characteristics of Scandium is it gets tarnished and burned easily if ignited.
a good ALD scandium oxide process that will produce low impurity films using reasonable deposition conditions. Sc 2O 3 has been depos-ited using chemical vapor deposition CVD from a -diketonate scandium source10 with relatively high purity and high growth rates above 450°C. ALD has been more of a challenge.

December 20, 2021 Posted by Madhu. The key difference between scandium and titanium is that scandium is a very light metal, whereas titanium is a very strong metal. Titanium is a metal that is known best for its strength. Some alloys of titanium can be as strong as steel. Although scandium is a strong metal, it is not as strong as titanium.
