To find the number of neutrons in an atom, you need to know the atomic number (which tells you the number of protons) and the atomic mass (which is the total number of protons and neutrons).
In this case, it seems you are working with an atom that has a mass number given (though it's not clearly shown in your prompt). The atomic mass for iron (Fe), which has an atomic number of 26, is approximately 55.845.
To calculate the number of neutrons, use the formula:
\[
\text{Number of neutrons} = \text{Mass number} - \text{Atomic number}
\]
If we take the atomic mass rounded to 56 (as most calculations would use the nearest whole number for such problems):
\[
\text{Number of neutrons} = 56 - 26 = 30
\]
So, based on this information, the answer would be **30** neutrons.
