Question Analysis
This question assesses the student's ability to determine the number of neutrons in an isotope given its atomic number and mass number.

Key Concept Explanation
The number of neutrons (N) in an isotope can be found by subtracting the atomic number (Z) from the mass number (A). The formula is: N = A - Z.

Step-by-step Solution
1. Identify the atomic number (Z) and mass number (A).
2. Use the formula: Number of neutrons (N) = Mass number (A) - Atomic number (Z).
3. Substitute the given va...
