Indium what? There's a few different isotopes. Up to 3.
You can find this by looking up the atomic weights to get the "average" for an atom In is 114.82 Zr is 91.224 If the atomic weights are close you may have to check for isotopes if tou think the questioner is really asking about individual atoms where the atomic mass varies. The isotopes of Indium are 113In and 115In Zr has a number of stable isotopes ranging from 90Zr to 94Zr So the lightest Indium isotope 113In is heavier than the heaviest isotope of Zr, 94Zr.
No, irradiation and radioactive iodine are not the same. Irradiation is the process of exposing something to radiation, while radioactive iodine is a form of iodine that emits radiation and is used in medical treatments, such as for thyroid conditions.
Indium has 3 valence electrons.
The atomic number of an element is determined by the number of protons in its nucleus. In this case, the isotope In-115 refers to indium with 115 protons. Therefore, the atomic number of isotope In-115 is 49.
Judging from its atomic number, indium has 49 protons and 49 electrons.
Indium has one unpaired electron. It has a configuration of [Kr] 4d10 5s2 5p1.
Indium forms the following bromides InBr3, indium tribromide, indium (III) bromide InBr, Indium monobromide, Indium(I) bromide InBr2, indium dibromide, In+ InBr4- , indium (I,III) bromide there are others which are not so well known
Indium always has 49 protons and usually has 49 electrons, but the number of electrons can change in indium ions.
In-115 isotope has 66 neutrons
caves have indium in it
