Identify the elements listed and their positions in group 16 of the periodic table. Group 16 elements are also known as the chalcogens.
Recall that group 16 elements include Oxygen (O), Sulfur (S), Selenium (Se), Tellurium (Te), and Polonium (Po).
Understand that the atomic number represents the number of protons in an element's nucleus and uniquely identifies the element.
Check the atomic numbers of the given elements: Oxygen has atomic number 8, Sulfur is 16, Selenium is 34, and Tellurium is 52.
Conclude that the element in group 16 with atomic number 8 is Oxygen.
