Solvent extraction from heavy rare-earth ion-adsorption clay leachate; DyF3 is reduced with Ca to metal.
Research Elements Dy · atomic number 66 Lanthanide · period 6 [Xe] 4f10 6s2 Shells: 2, 8, 18, 28, 8, 2 Valence electrons: 2 in the outer shell (6s2), and 10 in 4f10 Green dots are the outer shell's s and p electrons. Softer green dots are the d electrons of transition metals, and the d and f electrons of lanthanides and actinides: they often take part in bonding, but not always. Grey dots are the core. Ground-state configuration from the NIST Atomic Spectra Database (A. Kramida, Yu. Ralchenko, J. Reader and the NIST ASD Team). Abundance is the mole fraction of the element found as that isotope on Earth; digits in parentheses are the uncertainty in the last digits. Masses and abundances from NIST, Atomic Weights and Isotopic Compositions (J. S. Coursey, D. J. Schwab, J. J. Tsai and R. A. Dragoset, National Institute of Standards and Technology).Dysprosium
