Isotope
Variants of a particular chemical element which differ in neutron number but have the same number of protons.
Iron-56
An isotope of iron with a mass number of 56, known for its stability and abundant presence in the universe.
Neutrons
Subatomic particles found in the nucleus of an atom, with no electrical charge and a mass slightly larger than that of protons.
- Identify isotopes and perceive their importance regarding the count of neutrons.
- Tabulate the number of protons, neutrons, and electrons found in atoms or isotopes.
- Contrast isotopes by evaluating their mass numbers and comparing their neutron numbers.

Final Answer :
C
Explanation :
Iron-56 (Fe-56) has an atomic number of 26, which means it has 26 protons. The mass number of an isotope is the sum of its protons and neutrons. Therefore, to find the number of neutrons in iron-56, subtract the number of protons (26) from the mass number (56): 56 - 26 = 30 neutrons.
