››More information on molar mass and molecular weight. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together.
Yttrium is a chemical element with the symbol Y and atomic number 39. It is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a "rare-earth element". Yttrium is almost always found in combination with lanthanide elements in rare-earth minerals, and is never found in nature as a free element.
Because yttrium is an element, it can't be broken down any further by chemical means, but it can be combined with other elements. Yttrium is represented by the symbol ''Y'' and the atomic number 39.
Reaction of yttrium with air. Yttrium metal tarnishes slowly in air and burns readily to form yttrium (III) oxide, Y 2 O 3. 4Y + 3O 2 → 2Y 2 O 3. Reaction of yttrium with water. When finely divided, or heated, yttrium metal dissolves in water to form solutions containing the aquated Y(III) ion together with hydrogen gas, H 2.
What is Yttrium. Denoted by the chemical symbol Y, yttrium (pronounced as IT-ree-em) belongs to the family of transition and lanthanide metals. It is considered to be one of the rare earth elements having 50 isotopes, with yttrium-89 being the only stable one [3, 9].
