I think 75
The Fe(3+) cation has 26 protons, 30 neutrons (for the isotope Fe-56) and 23 electrons.
The number of neutrons in an atom of a certain element varies from one isotope of that element to another. Iron has stable isotopes Fe-54, Fe-56, Fe-57 and Fe-58 Fe-54 has 28 neutrons, Fe-56 has 30 neutrons, Fe-57 has 31 neutrons and Fe-58 has 32 neutrons.
Iron (Fe) has an atomic number of 26, which means it has 26 protons. The most common isotope of iron, iron-56 (Fe-56), has 30 neutrons (56 - 26 = 30). Therefore, a single Fe²⁺ atom, which has lost two electrons but retains the same number of protons and neutrons, still contains 30 neutrons.
Iron has 26 electrons; the number of neutrons is different for each isotope (number of neutrons = mass number - 26).
Iron (Fe) has an atomic number of 26, which means it has 26 protons and 26 electrons in its neutral state. The most common isotope of iron, iron-56, has 30 neutrons. Therefore, in total, iron has 26 protons, 26 electrons, and 30 neutrons.

30 neutrons in the most stable isotope of iron (Fe-56).

It is Iron, Fe.
Iron (Fe) has an atomic number of 26, which means it has 26 protons and 26 electrons in its neutral state. The most common isotope of iron, iron-56, has 30 neutrons. Therefore, in total, iron has 26 protons, 26 electrons, and 30 neutrons.
Iron-56 or 56Fe 56 protons makes it iron. If you add the protons and neutrons, you find the mass, which is 56.
In a neutral iron (Fe) atom, the number of protons is 26, which is the atomic number of iron. The number of neutrons can vary, but the most common isotope of iron, Fe-56, has 30 neutrons. Since the atom is neutral, it will have an equal number of electrons as the number of protons, so it also has 26 electrons.
Iron (Fe): atomic number 26 and of course has 26 protons.
These symbols are:5626U and Fe-56.
26 protons, 26 electrons in iron. Fe-56, the most stable isotope of iron, has 30 neutrons
