In-115 isotope has 66 neutrons
66
49 protons
10
It has 12 neutrons.
There are 18, 20 or 22 neutrons.
The number of neutrons depends on the atom. In general, mass number = atomic number + number of neutrons.
18 protons and 18, 20 or 22 neutrons.
Number of neutrons = Mass number - Number of protons = 127 - 53 = 74
Indium, atomic number 49, so 49 Protons. Atomic mass 115, so 115-49 = 66 Neutrons.
49 protons, 64 neutrons and 49 electrons.
Indium: 49 protons/electrons, 66 neutronsTin: 50 protons/electrons, 69 neutronsAntimony: 51 protons/electrons, 71 neutrons
There are the same amount of Protons as Electrons. Which is 49. And to find the neutrons. Subtract 49 from the atomic Number 113. = 64 neutrons. Take notes pimp. Steven Sterling

Judging from its atomic number, indium has 49 protons and 49 electrons.
Indium what? There's a few different isotopes. Up to 3.
indium has 49 protons, not electrons. strontium: group 2 peiod 5 is the closest Indium has 49 electrons
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 forms a number of chlorides InCl3, indium trichloride InCl, indium monochloride InCl2, indium dichloride
Indium, (In) atom number 49, has:49 protons (same as atom number)49 electrons (same as protons in the UNcharged neutral atom)113-49=64 neutrons in In-113 isotope or 115-49=66 neutrons in In-115 isotope,both are natural occurring isotopes of In (5% and 95% respectively).
