The Basics of Atomic Structure
In understanding the composition of an atom, it's crucial to know the role of protons, neutrons, and electrons. The atomic symbol for plutonium is represented as \(^{A}_{Z}\text{X}\), where:
- \(A\) = mass number (total number of protons and neutrons)
- \(Z\) = atomic number (number of protons)
- \(\text{X}\) = chemical symbol
In the case of plutonium (\(^{242}_{94}\text{Pu}\)):
- \(A = 242\)
- \(Z = 94\)
Calculating Neutrons
To find the number of neutrons in the nucleus, we can use the formula:
Neutrons = Mass Number - Atomic Number
Using the values for plutonium:
- Mass Number (\(A\)) = 242
- Atomic Number (\(Z\)) = 94
Now, plug in the values:
Neutrons = 242 - 94
This simplifies to:
Neutrons = 148
Conclusion
Thus, the number of neutrons in the nucleus of the plutonium nuclide \(^{242}_{94}\text{Pu}\) is:
- Answer: 148 (Option B)
This calculation confirms that option B is indeed the correct answer, as it accurately reflects the number of neutrons present in the plutonium nucleus.
