Quizplus · Accepted Answer

The compound name includes both iodine and fluorine, suggesting it is a compound made up of those elements. The prefix “tri-” indicates that there are three of one element, and since there are three iodines, the answer must include iodine. The suffix “-ide” indicates that fluorine is present as a negative ion (anion), which means it must have gained an electron to form fluoride. The only answer choice that fits this description is E, iodine trifluoride.
