It varies. Iron is element 26 with a relative Atomic Mass of 55.85
That means that the naturally occurring isotopes must have a range of neutrons.
92% of iron atoms have 30 neutrons, 8% have 28 neutrons; 2% have 31 neutrons and there is a small percentage <1% have 32 neutrons
30 neutrons in the most stable isotope of iron (Fe-56).
Iron-56 has 26 protons, 30 neutrons, and 26 electrons.
An atom of iron with a mass number of 54 contains 30 neutrons. This can be determined by subtracting the atomic number (26) from the mass number (54), which gives the number of neutrons in the nucleus.
26 protons, 26 electrons in iron. Fe-56, the most stable isotope of iron, has 30 neutrons
The atomic number of an isotope is the same as the element - so Iron-59 would have an atomic number the same as Iron - or 26.Iron-59 specifically isa radioisotope of iron having a half-life of 45 days; used in ferrokinetics tests to determine the rate at which iron is cleared from the plasma and incorporated in red cells. Symbol 59Fe.
In the most abundant isotope of iron, there are 26 protons and 26 neutrons.
91.72% of all iron has 30 neutrons. But there are also stable forms of iron with 31 and 32 neutrons.
It has 26 protons and 30 neutrons
30 neutrons in the most stable isotope of iron (Fe-56).
Iron-56 has 26 protons, 30 neutrons, and 26 electrons.
An atom of iron with a mass number of 54 contains 30 neutrons. This can be determined by subtracting the atomic number (26) from the mass number (54), which gives the number of neutrons in the nucleus.
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).
26 protons, 26 electrons in iron. Fe-56, the most stable isotope of iron, has 30 neutrons
The number of neutrons in an iron atom can vary depending on the isotope of iron. For the most common isotope, iron-56, there are 30 neutrons.
The element comes with 30 neutrons is iron. It also has 26 protons.
How many neutrons, not how much newtrons. Iron's atomic number is 26, so it has 26 protons; its atomic mass is approximately 56, which equals the number of protons and neutrons. 56 - 26 = 20 neutrons. While there are isotopes of iron with more or fewer neutrons, this is likely the answer you're expected to provide. If not, see Wikipedia "isotopes of iron".
