To determine the number of neutrons in an atom, you can use the formula:
\[ \text{Number of Neutrons} = \text{Atomic Mass} - \text{Atomic Number} \]
In this case, the atomic number of iron (Fe) is 26 (the number of protons), and the atomic mass is approximately 55.845. Plugging these values into the formula:
\[ \text{Number of Neutrons} = 55.845 - 26 \]
Calculating this gives:
\[ \text{Number of Neutrons} \approx 55.845 - 26 = 29.845 \]
Since the number of neutrons must be a whole number, we round it to the nearest whole number:
\[ \text{Number of Neutrons} \approx 30 \]
Therefore, the atom shown has approximately **30 neutrons**.
\[ \text{Number of Neutrons} = \text{Atomic Mass} - \text{Atomic Number} \]
