The initial deposits of metallic scandium and barium were confirmed with μSRXPS. After oxygen adsorption, the Sc 3p peaks shifted to higher binding energy (by >4 eV), indicating the formation of Sc 2 O 3 or a related compound. After heating to 800 C, the barium 4d peaks were no longer observed. The shifted Sc3p peak was also absent.

Therefore, the electron configuration of scandium (Sc*) in an excited state will be 1s 2 2s 2 2p 6 3s 2 3p 6 3d 1 4s 1 4p x1. The valency of the element is determined by electron configuration in the excited state. Here, scandium has three unpaired electrons. So the valency of scandium is 3. Scandium ion (Sc 3+) electron configuration

Electrons of Mev and gammarays of Mev were observed. Sc 48 emits approximately 14 gammarays per electron. All reactions associated with the scandium region are schematically summarized in a nuclear transmutation chart. Sc 47 : This radioactive isotope has been reported to have a halflife of days and to emit Mev electrons. ...
What is the Ionic Charge of Scandium (Sc)? And Why?
In ScCl 3, the Scandium (Sc) is bonded to Chlorine (Cl). You know that the ionic charge of Cl is 1. So you can easily say that the ionic charge of Sc should be 3+, then only it will get canceled out. Hence the ionic charge of Scandium in ScCl 3 is 3+. In ScF 3, the Scandium (Sc) is bonded to Fluorine (F). And again, you know that the ionic ...

Scandium is a soft metal with a silvery appearance. It develops a slightly yellowish or pinkish cast when oxidized by the air. Itis sensitive to weather and dissolves slowly in most dilute acids. It does not react with a mixture of nitric acid and 48% hydrofluoric acid, may be the result of the formation of a passive layer impermeable.

As upgrade for the Polytool, Scandium increases the mining speed as axe (+8), but decreases the attack damage and the mining speed as shovel, for ores and stones (2).. Recipe. Since it is an element, it can not be synthesized.
Scandium Kα and Kβ diagram, satellite and hypersatellite Xrays
Xray transitions from scandium due to proton, helium, and oxygen bombardment are reported. The oxygen +Sc spectrum displays the largest number of satellites including three hypersatellite transitions and in the He+Sc spectrum double electron transitions were observed. HartreeFockSlater calculated energies were used to assign the transitions.
