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.
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.
Iron-56 or 56Fe 56 protons makes it iron. If you add the protons and neutrons, you find the mass, which is 56.
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).

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.
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.
The element with 26 electrons, 29 neutrons, and 26 protons is iron (Fe), with an atomic number of 26.
The atomic number of iron is 26, so there are 26 protons in the nucleus of an iron atom. As the atomic mass of the isotope is 57 then the nucleus, which for all practical purposes is made up of protons and neutrons, each with an atomic mass of 1, contains 57-26 = 31 neutrons .57Fe is a stable isotope of Iron
The element with 26 electrons and 31 neutrons is iron (Fe), which has an atomic number of 26, corresponding to the number of electrons, and an atomic mass of approximately 57, which includes both protons and neutrons.
The particle you are describing is an atom of iron. The number of protons in an atom determines its atomic number, which is 26 for iron. The sum of protons and neutrons gives the atomic mass number, which is 56 for this iron atom.
