From the residues of the zinc-refining process by acid leach, solvent extraction and electrowinning.
Research Elements In · atomic number 49 Post-transition metal · period 5, group 13 [Kr] 4d10 5s2 5p1 Shells: 2, 8, 18, 18, 3 Valence electrons: 3 in the outer shell (5s2 5p1) 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).Indium
