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...

Crystals of the yttrium/aluminium/borate family are used for producing blue or UV light. To produce blue or UV light with the described crystal family a crystal of the family AMX(BO), wherein both A and also M stand for an element from the group Y, La, Ce, Pr, Nd, Pm, Sm, Eu,...
The Y–Y distances in the Y6octahedra varied from 3.30 to 3.85 Å and the shorter Y–Y separation (3.30 Å in shared edges) suggests a stronger Y–Y interaction connected to its phase stability.40,54Despite being congeners of the yttrium element, the Sc–Cl system has stable ...
