The Chalcogens are the elements found in Group 16 of the periodic table. The name "chalcogen" comes from the Greek words chalcos (meaning "ore") and gen (meaning "to form"), because many ores contain oxygen and sulfur, two of the chalcogens.
The elements in Group 16 include:
- Oxygen (O)
- Sulfur (S)
- Selenium (Se)
- Tellurium (Te)
- Polonium (Po)
These elements share some chemical properties, such as forming compounds by gaining two electrons, leading to a common oxidation state of -2. Oxygen, the most well-known chalcogen, is a vital component of water and air, while sulfur is widely used in industries like rubber manufacturing and fertilizers.

Chalcogens: Definition and Group
Chalcogens are a group of elements in the periodic table that are known for their diverse chemical properties. They are positioned in Group 16.
Elements of Group 16
- The chalcogens include the following elements:
- Oxygen (O)
- Sulfur (S)
- Selenium (Se)
- Tellurium (Te)
- Polonium (Po)
Characteristics of Chalcogens
- Reactivity: Chalcogens exhibit varying levels of reactivity. Oxygen, for instance, is highly reactive and essential for combustion, while polonium is radioactive.
- Allotropes: Some chalcogens, such as sulfur and phosphorus (though phosphorus is technically in Group 15), form multiple allotropes, which are different structural forms of the same element.
- Compounds: Chalcogens readily form compounds with metals and nonmetals, including oxides, sulfides, and selenides.
Importance in Biological and Industrial Processes
- Oxygen: Vital for respiration in aerobic organisms.
- Sulfur: Key component in amino acids and proteins.
- Selenium: Important for certain enzymes and has antioxidant properties.
Conclusion
In summary, chalcogens are essential elements located in Group 16 of the periodic table, playing critical roles in both biological systems and industrial applications. Understanding their properties and significance can provide insight into various chemical processes and environmental interactions.
