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

How many neutrons are present in atom of iron 54?
The isotope iron-54 has 28 neutrons.
How many protons neutrons and electrons does iron 56 have?
Iron-56 has 26 protons, 30 neutrons, and 26electrons.
How many neutrons are in the nucleus of a typical iron atom?
30 neutrons in the most stable isotope of iron (Fe-56).
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
What is the mass number of an iron that has 29 neutrons?
The mass number of an iron that has 29 neutrons would be 55. You just take the atomic number of iron, which is 26, and add that to the number of neutrons, which is 29, and you get 55.
How many neutrons are present in atom of iron 54?
The isotope iron-54 has 28 neutrons.
How many protons neutrons and electrons does iron 56 have?
Iron-56 has 26 protons, 30 neutrons, and 26electrons.
How many protons and neutrons are in iron?
In the most abundant isotope of iron, there are 26 protons and 26 neutrons.
How many neutons in a iron?
91.72% of all iron has 30 neutrons. But there are also stable forms of iron with 31 and 32 neutrons.
How many protrons and neutrons does iron have?
It has 26 protons and 30 neutrons
How many neutrons are in the nucleus of a typical iron atom?
30 neutrons in the most stable isotope of iron (Fe-56).
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 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
What element has 30 neutrons?
The element comes with 30 neutrons is iron. It also has 26 protons.
How much newtrons are in iron?
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".
How many atoms in iron?
26 protons 26 electrons and 30 neutrons
What is the mass number of an iron that has 29 neutrons?
The mass number of an iron that has 29 neutrons would be 55. You just take the atomic number of iron, which is 26, and add that to the number of neutrons, which is 29, and you get 55.
