Indium (49 In) consists of two primordial nuclides, with the most common (~ 95.7%) nuclide (115 In) being measurably though weakly radioactive. Its spin-forbidden decay has a half-life of 4.41×10 14 years, much longer than the currently accepted age of the Universe. The stable isotope 113 In is only 4.3% of
The darker more stable isotope region departs from the line of protons (Z) = neutrons (N), as the element number Z becomes larger. ... indium: 1: 1: 115 In: 113 In: 57:
Indium has 39 known isotopes, ranging in mass number from 97 to 135. Only two isotopes occur naturally as primordial nuclides: indium-113, the only stable isotope, and indium-115, which has a half-life of 4.41 × 10 14 years, four orders of magnitude greater than the age of the Universe and nearly 30,000 times greater than half life of thorium ...
The graph reflects the fact that elements with more than 20 protons either have more neutrons than protons or are unstable. ... Indium-113 Indium-115 (B) – long ...
The only stable nuclides having an odd number of protons and an odd number of neutrons are hydrogen-2, lithium-6, boron-10, nitrogen-14 and (observationally) tantalum-180m. This is because the mass–energy of such atoms is usually higher than that of their neighbors on the same isobaric chain, so most of them are unstable to beta decay.
The number of protons (Z column) and number of neutrons (N column). energy column The column labeled "energy" denotes the energy equivalent of the mass of a neutron minus the mass per nucleon of this nuclide (so all nuclides get a positive value) in MeV , formally: m n − m nuclide / A , where A = Z + N is the mass number.
Many manufacturers are expected to turn to other FDA-approved artificial dyes, like Red 40, to keep production costs low. However, some may opt for more natural alternatives, despite potential ...
