Do hallogens normally stick to the octet guideline when they're surrounding the central and surrounding atom(s)? Or does that change when it's a central atom?

Phosphorus and onwards can violate the octet rule, so this doesn't include the Halogen fluorine. Generally, when atoms have Lewis structures that violate the octet rule, it's when they're the central atom eg. SO42-. Also, you can have violations in the octet rule in a linear molecule like ClO.
