Indium was discovered by Ferdinand Reich and H.T. For indium:a) Write the electron configuration.b) Predict the ion(s) of indium.c) Write out the electron configurations of the ion(s). Indium is named for the brilliant indigo line in the element's spectrum. Indium atoms have 49 electrons and the shell structure is 2.8.18.18.3. The indium atom has a radius of 162.6 pm and a Van der Waals radius of 193 pm. For indium atoms (atomic number = 49, electrons = 49) 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5p^1 . ... Indium(III) salts are known to be toxic to the kidneys. This video tutorial will help you determine the electronic configuration of the Indium atom. Word Origin: Latin indicum. There are 118 elements in the periodic table. Remember, try to review about orbitals, valence electrons, shells and sub-shells as well. Indium was discovered by Ferdinand Reich and Hieronymous Theodor Richter in 1863. Resources Electron configuration for N^3-: 1s^2 2s^2 2p^6. Iridium Electronic configuration. Indium was discovered by Ferdinand Reich and Hieronymous Theodor Richter in 1863. Indium forms InAs, which is found in photoconductors in optical instruments. Richter in 1863. Richter in 1863. The electron configuration for the iron(III) ion is: "1s"^2"s"^2"2p"^6"3s"^2"3p"^6"3d"^5" The element iron, Fe, has the atomic number 26, which is the number of protons in its atomic nuclei. In order to form a 3^+ ion, it must lose three electrons. For indium 3+ (atomic number = 49, charge = +3, number of electrons = 49-3 = 46).
