Does indium have isotopes?
Natural indium is a mixture of two isotopes: indium-113 (4.28 percent) and indium-115 (95.72 percent). The periodic table is made up of 118 elements.
What ion does indium form?
In compounds, indium most commonly donates the three outermost electrons to become indium(III), In3+. In some cases, the pair of 5s-electrons are not donated, resulting in indium(I), In+.
How many stable isotopes does indium have?
two stable isotopes
Indium has two stable isotopes and one of them, In-113, is used for the production of radioisotopes.
What is the most abundant isotope of indium?
113
Indium (49In) consists of two primordial nuclides, with the most common (~ 95.7%) nuclide (115In) being measurably though weakly radioactive. Its spin-forbidden decay has a half life of 4.41×1014 years. The stable isotope 113In is only 4.3% of naturally occurring indium.
What are isotopes answer?
Isotopes are versions of the same element. They have the same number of protons and electrons as the element but different mass numbers and number of neutrons. The number indicates the isotope’s mass number.
Where is indium-111 produced?
cyclotron
Indium-111 is produced in a cyclotron using a cadmium-112 target which is bombarded with protons to produce indium-111 by the (p,2n) reaction. The energies of the γ-ray emissions (171 and 245 keV) are higher than that of technetium-99m. Indium-111 forms complexes in which indium is present in the + 3 oxidation state.
Who discovered indium-111?
Chemically, indium is similar to gallium and thallium, and it is largely intermediate between the two in terms of its properties. Indium was discovered in 1863 by Ferdinand Reich and Hieronymous Theodor Richter by spectroscopic methods.
