The meaning of YTTRIUM is a metallic element with atomic number 39 usually included in the rare-earth group that occurs usually with other rare earth elements in minerals and is used especially in phosphors, YAG lasers, alloys, and treatments for certain
Elements in the periodic table usually exhibit strong similarities to others in the same vertical group - however in this regard yttrium is different, and it does not correspond closely to scandium, the element directly above it in the table. [1]...
Yttrium is a chemical element; it has 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".[5] Yttrium is almost always found in combination with lanthanide elements in rare-earth...
The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element. The number of protons determines the element, but the number of neutrons in the atom of any one element can vary. Each variation is an isotope. About a dozen radioactive isotopes of...
