Group VI, also known as the chalcogens, is a category of elements in the periodic table that includes oxygen, sulfur, selenium, tellurium, and polonium. These elements are found in group 16 and are known for their diverse chemical properties. They play essential roles in various biological and geological processes. The chalcogens typically have six valence electrons, which allows them to form a variety of compounds, including oxides and sulfides. Oxygen is vital for respiration in living organisms, while sulfur is important in the formation of amino acids and proteins.
