The Fe(3+) cation has 26 protons, 30 neutrons (for the isotope Fe-56) and 23 electrons.
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.
Fe 2+ (Iron) has... 26 protons 24 electrons 30 neutrons
Iron has 26 electrons; the number of neutrons is different for each isotope (number of neutrons = mass number - 26).
Iron-56 or 56Fe 56 protons makes it iron. If you add the protons and neutrons, you find the mass, which is 56.

26 protons, 26 electrons in iron. Fe-56, the most stable isotope of iron, has 30 neutrons

It doesn't matter if it's 56Fe or 49Fe; the number of protons in an atom of iron will remain constant. Why? Because if there was one more electron, it wouldn't be Fe anymore: it'd be cobalt (Co). The number of protons determines the element, the only thing that can change regarding the nuclear makeup of an atom without changing the element is the number of electrons. The 56 stands for the atomic weight of that particular isotope of iron. If each neutron and each proton weigh 1 amu each, then the atomic weight minus the number of protons will give you the number of neutrons.
I am understanding you to mean an iron-57 ion with a charge of 3+.The atomic number of Fe is 26, which means that all Fe atoms or ions have 26 protons in their nuclei.In a neutral Fe atom, the number of electrons would be the same as the number of protons, which is 26. The charge on the Fe ion is 3+, which means the Fe atom has given up 3 electrons. So the number of electrons in an Fe3+ ion is 26-3, which is 23.The mass number of iron-57 = 57. The mass number is the sum of protons and neutrons in the atomic nuclei of iron-57 atoms. We know the number of protons is 26. The number of neutrons = mass number - the number of protons, which is 57-26 = 31 neutrons.To summarize:The number of protons in all Fe atoms is 26.The number of electrons in an any Fe3+ ion is 23.The number of neutrons in an iron-57 atom is 31.
An elemental iron (Fe) atom. The number of protons determines the element's identity, and the number of electrons determines its valence state.
The ion Fe(-) doesn't exist.
26 protons, 26 electrons and 29 neutrons in 26Fe55 isotope
The number of protons in an atom will always be the same with any atom of the same element. The number of protons is an elements defining characteristic; a different number of protons will produce a different element. So it is not necessary to know the specific isotope (which is given by the mass number), because all atoms, ions, and isotopes of iron will all have 26 protons, the same as the atomic number.
