Scandium oxide (Sc2O3) contains two scandium (Sc) atoms and three oxygen (O) atoms in its molecular formula. To find the percent composition of scandium, first calculate the molar mass: the molar mass of Sc is approximately 45.0 g/mol, and that of O is about 16.0 g/mol. Thus, the molar mass of Sc2O3 is (2 × 45.0) + (3 × 16.0) = 114.0 g/mol. The percent scandium is then (90.0 g/mol / 114.0 g/mol) × 100%, which is approximately 78.95%.

What does scandium 3 oxide mean in terms of electrons gained and lost?
Scandium(III) oxide, represented as Sc₂O₃, indicates that scandium has lost three electrons to form a Sc³⁺ ion, while oxygen typically gains two electrons to form O²⁻ ions. In the compound, two Sc³⁺ ions combine with three O²⁻ ions to achieve electrical neutrality. Thus, scandium in this oxide is in a +3 oxidation state, while oxygen is in a -2 oxidation state.
What color is scandium?
what is the color of scandium?
Does scandium rust?
Scandium is a highly reactive metal, but it does not rust in the same way as iron or steel. Instead, when exposed to air, it forms a thin layer of oxide on its surface which can help protect it from further corrosion. However, prolonged exposure to moisture and other corrosive substances can still lead to the deterioration of scandium.
Is scandium oxide molecular?
Yes, scandium oxide - Sc2O3 has molecules.

What is Sc2O3?
Sc2O3 is the chemical formula for scandium oxide, a compound composed of scandium and oxygen. It is a white powder with applications in the production of high-refractive-index glass and ceramics, as well as in the manufacture of solid oxide fuel cells.
What does scandium obtained from?
Scandium is usually found with rare earth and uranium compounds. One by-product of these metals is scandium oxide (Sc2O3) and it usually traded in this form. To obtain metallic scandium, the oxide is first converted to a fluoride and then reduced using calcium.

Is scandium combustible?
Scandium metal is not combustible, but it can react with air to form a protective oxide layer on its surface. This oxide layer can prevent further reaction with oxygen. However, finely divided scandium dust or powder may pose a fire hazard if exposed to a strong ignition source.
