Step 1
The octet rule states that atoms tend to have eight electrons in their valence shell to achieve a stable electronic configuration. Let's analyze each option to determine which one does not violate the octet rule.
Step 2
A. SF₄: Sulfur has six electrons in its outer shell. By sharing four electrons with four fluorine atoms, sulfur achieves a stable octet. However, each fluorine atom needs one more electron to complete its octet, so this compound does not satisfy the octet rule for all atoms.
Final Answer
The central atom in option B, ICl₄⁻, does not violate the octet rule.
