How many protons electrons and neutrons does In have? 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 11 â¦ 5-49=66 neutrons in In-115 isotope, both are natural occurring isotopes of In (5% and 95% respectively).
