Question Analysis
This question tests the student's ability to name an isotope given the number of protons and neutrons.

Key Concept Explanation
Isotopes are named by the element name followed by the mass number. The mass number is the sum of the number of protons and neutrons in the nucleus.

Step-by-step Solution
1. Identify the number of protons (Z) and neutrons (N): Z = 16, N = 18.
2. Calculate the mass number (A) using the formula A = Z + N: A = 16 + 18 = 34.
3. Name the isotope by combining the element name (sulfur) and the mass number: sul...
