The isotope iron-54 has 28 neutrons.
30 neutrons in the most stable isotope of iron (Fe-56).
26 protons, 26 electrons in iron. Fe-56, the most stable isotope of iron, has 30 neutrons
A stable magnesium atom has 12, 13 or 14 neutrons. The atom with 12 neutrons is the most common one.
The number of neutrons in an atom of mercury depends on the isotope. The most common mercury isotope has 122. The average number of neutrons in an atom of mercury is about 120.
An average phosphorus atom has 15 protons and 16 neutrons, and it has 31 nucleons.
30 neutrons in the most stable isotope of iron (Fe-56).
This depends on the individual Atom.
30 neutrons in Ni-58 isotope.
The number of neutrons will vary for every isotope of an atom and is not possible to generalize for all the elements.
"Used" is the wrong term to be used in this case. An atom is MADE up of protons,neutrons and electrons. Also, the number of protons or neutrons present in an atom depends on which atom is it or of which element it is.
The number of neutrons in an atom of a certain element varies from one isotope of that element to another. Iron has stable isotopes Fe-54, Fe-56, Fe-57 and Fe-58 Fe-54 has 28 neutrons, Fe-56 has 30 neutrons, Fe-57 has 31 neutrons and Fe-58 has 32 neutrons.
26 protons, 26 electrons in iron. Fe-56, the most stable isotope of iron, has 30 neutrons
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).
In iron bromide FeBr2, there is 1 iron atom present.
If its just iron then there is only one type of atom: iron atoms
A typical atom of iodine contains 74 neutrons.
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.
