Group 17

For group 17 elements, I understand that they can only form one bond with other elements since they already have 7 electrons; however, is there any exceptions that would allow group 17 elements to obtain a double bond or triple bond? Just curious

Yes, in some cases, group 17 elements can form double or triple bonds because some of them can have an expanded octet depending on where they are on the periodic table. For example, I believe Iodine can form a double bond because it is able to have an expanded octet.

Hope this helps!

To expand, the elements under Flourine in group 17 are all exceptions to the octet rule.
