Answer: Nuclear fusion fuel and luminescent markers (radioactive beta emitter).
- A Nuclear fusion fuel and luminescent markers (radioactive beta emitter)
- B As a food preservative that extends shelf life through irradiation
- C As a catalyst that accelerates hydrogenation reactions
- D As an industrial solvent for non-polar organic extractions
Correct answer: A. Nuclear fusion fuel and luminescent markers (radioactive beta emitter)
Explanation: Tritium (3H, T) is a radioactive hydrogen isotope used in thermonuclear fusion (D-T reaction) and in self-luminous watch dials and exit signs.
Each water molecule's O-H bonds (covalent, solid) can hydrogen-bond (dashed) to neighbouring molecules, forming an extended network responsible for water's unusually high boiling point and density anomaly.
Concept context
The simplest and most abundant element in the universe. Study its unique position in the periodic table, isotopes (protium, deuterium, tritium), properties of water and hydrogen peroxide, and industrial uses.
