Group+16

GROUP 16: THE OXYGEN GROUP



**The Oxygen Group Consists of the elements oxygen, sulfur, selenium, tellurium, and polonium.

Nonmetals in the group are oxygen and sulfure, while polonium, selenium, and tellurium are the metallooid semiconductors. __Metalloid Semiconductor__ - element is between a metal and insulator

However, tellurium and selenium are sometimes referred to as metals, depending on what from they are in.

Members of Group 16 have very similar electron configuration patterns, which gives them very similar chemical behaviors.**
