To determine the number of neutrons in an atom, you'll need to know its atomic mass (usually represented as the atomic number plus the number of neutrons) and its atomic number (which represents the number of protons). The number of neutrons can be calculated using the following formula:
\[
\text{Number of neutrons} = \text{Atomic mass} - \text{Atomic number}
\]
If the atomic mass is approximately 55.845 and the atomic number is 26 (which corresponds to iron, Fe), then:
\[
\text{Number of neutrons} = 55.845 - 26 \approx 29.845
\]
Since we can't have a fraction of a neutron, we round this value to 30.
So, the number of neutrons in the atom shown (assuming it corresponds to iron) is **30**.
\[
\text{Number of neutrons} = \text{Atomic mass} - \text{Atomic number}
\]
