Understand that the atomic number of an element is the number of protons found in the nucleus of an atom of that element.
Recall that the atomic number is unique to each element and is used to define the element's identity.
Consult the periodic table to find sulfur (S), which is located in period 3 and group 16.
Identify the atomic number of sulfur on the periodic table, which is typically listed above the element symbol.
Recognize that the atomic number of sulfur is 16, indicating it has 16 protons in its nucleus.
