Indium atoms have 49 electrons and the shell structure is 2.8.18.18.3. Resources Richter in 1863. The number of electrons in each of indium's shells is [2, 8, 18, 18, 3] and its electron configuration is [Kr] 4d 10 5s 2 5p 1. A neutral iron atom has 26 protons and 26 electrons. Radioactive In-111 is used as a radiotracer in nuclear medicine to label white blood cells and proteins. For indium 3+ (atomic number = 49, charge = +3, number of electrons = 49-3 = 46). Indium has the chemical symbol In and the atomic number 49. Each element has a unique atomic structure that is influenced by its electronic configuration, which is the distribution of electrons across different orbitals of an atom. The ground state electron configuration of ground state gaseous neutral indium is [Kr].4d ⦠It has the electron configuration [Kr] 2s 2 2p1 and may adopt the +1 or +3 oxidation state; however, the +3 state is more common. The indium atom has a radius of 162.6 pm and a Van der Waals radius of 193 pm. Indium was discovered by Ferdinand Reich and H.T. Iridium Electronic configuration. Remember, try to review about orbitals, valence electrons, shells and sub-shells as well. 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. Electron Configuration: [Kr] 5s 2 4d 10 5p 1. Indium was discovered by Ferdinand Reich and Hieronymous Theodor Richter in 1863. Includes Elements, 7.31, Poor metals, 1.78, Group 13, Primordial, Period 5, 0.233, 0.25, 114.818, 429.75, [Kr] 4d 10 5s 2 5p 1 , 2345 and 49. The number of electrons in each of indium's shells is [2, 8, 18, 18, 3] and its electron configuration is [Kr] 4d 10 5s 2 5p 1.
