chalcogens
Oxygen family or chalcogen
selenium is in the group IV so it belongs to the Chalcogen family :)
Selenium was named after the Greek word "selene," which means moon. This is because selenium's properties were found to be similar to tellurium, which was named after the Earth, and sulfur, which was named after the Sun. The name selenium reflects its position in the same chemical group as tellurium and sulfur.

Sulfur Oxide
To locate a family of elements in the periodic table, identify the column (group) where the elements are found. The oxygen family, also known as Group 16, includes the elements oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and polonium (Po). Sometimes, it also includes the synthetic element livermorium (Lv). These elements share similar chemical properties due to their position in the same group.
Sulfur trioxide
The family name for the element sulfur is the chalcogens.
Hydrogen, helium, boron, carbon, nitrogen, oxygen, fluorine, neon, phosphorus and sulfur are ten non metals in the order of increasing atomic number.
As the name implies, its constituent elements are sulfur and oxygen. Sulfur trioxide has the formula SO3, which means it contains one sulfur atom and three oxygen atoms.
The combustion of sulfur is called sulfur combustion or sulfur burning. When sulfur combusts, it reacts with oxygen to produce sulfur dioxide gas.
