For example, Mendeleev predicted the element's molecular weight would be 44 and that it would form one oxide with formula Eb 2 O 3; scandium has molecular weight 45, and forms scandium oxide, Sc 2 O 3. Some of Mendeleev's predictions were even more detailed.

Samarium is a chemical element with the symbol Sm and atomic number 62. It is a moderately hard silvery metal that slowly oxidizes in air. Being a typical member of the lanthanide series, samarium usually assumes the oxidation state +3. Compounds of samarium(II) are also known, most notably the monoxide SmO, monochalcogenides SmS, SmSe and SmTe, as well as samarium(II) iodide.
Scandium (atomic number 21, symbol Sc) is a rare transition metal with a silvery white color. Other rare elements are lutetium, ytterbium, thulium, erbium, and holmium. It is considered a rare element because it occurs in the same ores as other rare earth elements and has the same properties.

Scandium is a soft, lightweight, silvery-white metal, similar in appearance and weight to aluminum. It is represented by the chemical symbol Sc and has one naturally occurring isotope. Although its occurrence in crustal rocks is greater than that of lead, mercury, and the precious metals, scandium …
He called this new element eka-silicon, after observing a gap in the periodic table between silicon and tin: Similarly, Mendeleev discovered gallium (eka-aluminum) and scandium (eka-boron) on paper, because he predicted their existence and their properties before their actual discoveries.
Scandium: Scandium (Sc), chemical element, a rare-earth metal of Group 3 of the periodic table. 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 Sc2O3 oxide on the surface. The

Facts Date of Discovery: 1879 Discoverer: Lars Nilson Name Origin: From Scandinavia Uses: No uses known Obtained From: minerals (thortveitile, wiikite) Related Links I currently do not know of any links for Scandium. If you do, please let me know MLA Format for Citing This Page
Scandium was discovered by Lars F. Nilson in 1879, in Uppsala, Sweden. Nilson was studying the rare earth elements, attempting to isolate ytterbium from the minerals euxenite and gadolinite.. Part of Nilson's method required the preparation of erbia (erbium oxide) from the minerals, which was then reacted to form erbium nitrate.
