Which element has three isotopes?
Correct answer: A. H
- A. H
- B. Zn
- C. Cl
- D. None of these options are correct
Explanation
The element with three isotopes is hydrogen (H). Hydrogen has three isotopes: protium (H-1), deuterium (H-2), and tritium (H-3). Protium is the most common and abundant isotope of hydrogen, while deuterium and tritium are less common.Protium has one proton and no neutrons, deuterium has one proton and one neutron, and tritium has one proton and two neutrons.Therefore, option A) H (Hydrogen) is the correct answer as it is the element that has three isotopes.
