49
Remember an atom has the same number of electrons as protons.
Indium has 49 protons and electrons.
Judging from its atomic number, indium has 49 protons and 49 electrons.
Indium, atomic number 49, so 49 Protons. Atomic mass 115, so 115-49 = 66 Neutrons.
Indium always has 49 protons and usually has 49 electrons, but the number of electrons can change in indium ions.
indium has 49 protons, not electrons. strontium: group 2 peiod 5 is the closest Indium has 49 electrons
The element that has 49 protons is the one with the atomic number 49. On the Periodic Table, atomic number 49 belongs to indium, In.
Indium: 49 protons/electrons, 66 neutronsTin: 50 protons/electrons, 69 neutronsAntimony: 51 protons/electrons, 71 neutrons
In-115 isotope has 66 neutrons
So, all you have to look at is at the atomic number of the elements on the periodic table, which it is at the top of the symbol on the P.T, and that is the number of protons and electrons! Now, to find the number of neutrons, you have to find the number at the bottom of the element symbol called the atomic mass no. and you take away that by the top number.
One indium atom consists of 49 protons, 49 electrons, and typically 66 neutrons in its nucleus.
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.
Indium, a element of the new mulennium. -B.P.R
