Shavings or turnings of the metal can ignite in air when they exceed 400 °C Finely divided yttrium is very unstable in air.    Date of Discovery    Atomic Mass Yttrium is almost always found in combination with lanthanide elements in rare-earth minerals, and is never found in nature as a free element. Note that, ionization energies measure the tendency of a neutral atom to resist the loss of electrons. Atomic Structure of Yttrium. The nucleus consists of 39 protons (red) and 50 neutrons (blue). Gadolinium. Yttrium is a monoisotopic element and its atomic weight is determined solely by its isotope 89 Y.  Links, Show Table With: Anatomy of the Atom Answers many questions regarding the structure of atoms. For stable elements, there is usually a variety of stable isotopes. SOURCE Atomic weights of the elements: Review 2000 by John R de Laeter et al. Yttrium oxide.

Natural yttrium (39 Y) is composed of a single isotope yttrium-89. Atomic weight of Yttrium is 88.90584 u or g/mol. Mira is a type of giant red star where most of the yttrium is concentrated in the solar system. The surface atomic structure of thin layers of three-dimensional yttrium silicide epitaxially grown on Si(111) 7x7 has been investigated by means of dynamical low-energy electron diffraction analysis. The chemical symbol for Yttrium is Y . The atomic layer deposition (ALD) of yttrium oxide (Y2O3) is investigated using the liquid precursor Y(EtCp)2(iPr-amd) as the yttrium source with thermal (H2O) and plasma-enhanced (H2O plasma and O2 plasma) processes, respectively. This page was created by Yinon Bentor. However, this assumes the atom to exhibit a spherical shape, which is only obeyed for atoms in vacuum or free space.    Electron Configuration The Y‐O bond length is about 2.2 Å and the coordination number is 6.3. Y is the only stable isotope, and the only isotope found in the Earth's crust. What is Yttrium? Yttrium is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a “rare-earth element”.
