Solve this multiple-choice question and choose the correct option.

What is being asked?Pick the option that is not a hydrogen isotope. Given data Hydrogen isotopes: protium (¹H), deuterium (²H or D), tritium (³H or T) Concept/ApproachHydronium is a polyatomic ion (H3O+) formed when H+ associates with water; it is not an isotope (same element with different mass numbers). Final AnswerHydronium (H3O+)
