Q. Consider the following statements regarding Rhenium:

1. It has the highest boiling point of all elements.
2. It is used in superalloys for jet engine turbines.
3. Rhenium is naturally abundant and easy to mine.

Which of the above statements is/are correct?
Answer: 1 and 2 only
Notes: Rhenium has the highest boiling point among all elements (5,597°C), making statement 1 correct. It is extensively used in superalloys for jet engine turbines due to its high-temperature properties, confirming statement 2. However, Rhenium is among the rarest elements in Earth’s crust and is not naturally abundant or easy to mine, making statement 3 incorrect.
