Iron is element number 26, so it has 26 protons and 26 electrons. (If the protons don't match the electrons, the atom is ionized, not neutral as usually assumed.)
The number of neutrons varies in the different isotopes of the element. On Earth, the proportions are: (Rounded numbers, see source for exact.)
- 92% of 56Fe, with 30 neutrons
- 6% of 54Fe, with 28 neutrons
- 2% of 57Fe, with 31 neutrons
- 1% of 58Fe, with 32 neutrons
Other numbers of neutrons are possible, but unstable. (54Fe may be unstable as well, but this hasn't been verified experimentally.)
These numbers result in an atomic weight of 55.8, from the most common 56Fe isotope with a small contribution from the lighter ones.

How many protons and neutrons and electrons does iron?
Iron has 26 protons, and since protons and electrons are usually the same there are 26 electrons in Iron. There is 30 neutrons. So protons=26, electrons=26, neutrons=30.
What atom had 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.
How many protons are there in an atom of iron?
26 It has 26 protons, 26 electrons and (mostly) 30 neutrons, but 28, 31 and 32 neutrons are natural isotopes of iron as well (though less than 10%).
How many protons neutrons electrons fe 2?
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.
How many atoms in iron?
26 protons 26 electrons and 30 neutrons
How many protons neutrons and electrons does iron 56 have?
Iron-56 has 26 protons, 30 neutrons, and 26electrons.
How many protons electrons and neutrons are there in a iron atom?
26 protons, 26 electrons in iron. Fe-56, the most stable isotope of iron, has 30 neutrons
How many electrons protons and neutrons respectively are in the iron III ion 56FE3 plus?
23 electrons, 26 protons, 30 neutrons.
How many number of protons are in iron?
It has 26 Protons, 26 Electrons, and 30 Neutrons.
What atom had 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.
How many protons and neutrons and electrons does iron?
Iron has 26 protons, and since protons and electrons are usually the same there are 26 electrons in Iron. There is 30 neutrons. So protons=26, electrons=26, neutrons=30.
How many neutrons and electrons are in iron?
The atomic number of iron is 26 whereas the mass number of it is 56. Therefore it has 26 electrons and 30 neutrons (56-26).
How many protons are there in an atom of iron?
26 It has 26 protons, 26 electrons and (mostly) 30 neutrons, but 28, 31 and 32 neutrons are natural isotopes of iron as well (though less than 10%).
How many protons neutrons electrons fe 2?
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.
How many protons neutrons and electrons in 40 Ar?
18 protons 18 electrons 22 neutrons
What is the mass number of an iron isotope with 26 protons 31 neutrons ans 24 electrons?
Number of protons + neutrons = mass number 26 protons + 31 neutrons 57
How many atoms in iron?
