What is the common oxidation state of Group 17 elements?

Step 1: Identify Group 17 elements, which are also called halogens. These include fluorine, chlorine, bromine, iodine, and astatine.
Step 2: Understand what oxidation state means. It refers to the charge an atom would have if all bonds were ionic.
Step 3: Recognize that halogens have 7 electrons in their outer shell and need 1 more electron to complete it.
Step 4: When halogens gain 1 electron, they achieve a full outer shell and acquire a charge of -1.
Step 5: Conclude that the common oxidation state of Group 17 elements is -1.
