Which of the following is most similar to a hydrogen ion, H+ ?(1 point) Responses A proton, p+ A proton, p raised to the plus power A fluoride ion, F− A fluoride ion,r A lithium ion, Li+ A lithium ion, cap l i raised to the plus power A sodium ion, Na+

A hydrogen ion (H⁺) is essentially a proton, as it is formed when a hydrogen atom loses its electron. Therefore, the option that is most similar to a hydrogen ion, H⁺, is:

**A proton, p+**

This is because H⁺ is just a proton, while the other options involve different elements or compounds.
