Indium always has 49 protons and usually has 49 electrons, but the number of electrons can change in indium ions.
The atomic number of indium is 49. That means it has 49 protons. In a neutral atom, the number of protons and electrons are equal, so a neutral atom of indium will have 49 electrons, too.
Indium: 49 protons/electrons, 66 neutronsTin: 50 protons/electrons, 69 neutronsAntimony: 51 protons/electrons, 71 neutrons
A neutral atom with 49 electrons will have 49 protons. The number of protons and electrons are always the same in a neutral atom. If the number of protons is not matched by the number of electrons, then the atom is charged and is called an ion. Further, if protons outnumber electrons, the atom is positively charged and is a positive ion. For situations where electrons outnumber protons, the opposite is true. The element with 49 protons in it is indium, by the way.
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.
3 valence electrons
Indium what? There's a few different isotopes. Up to 3.
Judging from its atomic number, indium has 49 protons and 49 electrons.
Indium has 49 protons and electrons.
Indium 49 protons 49 electrons is correct. zinc will have 30 protons and 30 electrons.

49 Remember an atom has the same number of electrons as protons.
49 protons, 64 neutrons and 49 electrons.
indium has 49 protons, not electrons. strontium: group 2 peiod 5 is the closest Indium has 49 electrons
