Precipitated from PGM chloride solution as Pd(NH3)2Cl2, redissolved and reprecipitated to purify, then reduced with hydrogen or hydrazine to sponge.
Research Elements Pd · atomic number 46 Transition metal · period 5, group 10 [Kr] 4d10 Shells: 2, 8, 18, 18 Valence electrons: 10 in 4d10 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).Palladium
