O and S are essential to all forms of life. About 0.09 % of sulphur is found in seawater in the form of sulphates. Their compounds are known as chalcogenides. The group 16 elements of modern periodic table consist of 5 elements oxygen, sulphur, selenium, tellurium and polonium. During the combination with some elements, the evolution of heat energy takes place, this process is known as combustion. An exception is the "iron group", which usually refers to "group 8", but in chemistry may also mean iron, cobalt, and nickel, or some other set of elements with similar chemical properties. Oxygen is also found as a triatomic molecule (O3) in traces, it is known as ozone. Occurrence. Why Oxygen shows +2 oxidation state inspite of high … When we call them elements, it is essential to note that oxygen is a gas while other group members are solids. This group consists of oxygen, sulphur, selenium, tellurium, and polonium. Polonium and its compounds are radioactive, extremely toxic, and need to be handled with care. This lesson will discuss the general trend in oxidation state, Catenation property and Allotrophic forms of. ‘Oxygen' and "sulfur" are non-metals, "selenium" and "tellurium" are metalloids and "polonium" is a metal under typical conditions.
