Single correct option

Consider the following statements:
1. Mercury is the only metal that is liquid at room temperature.
2. Bromine is the only non-metal that is liquid at room temperature.
Which of the statements is/are correct?
  1. A. 1 only
  2. B. 2 only
  3. C. Both 1 and 2
  4. D. Neither 1 nor 2
Show answer and solution

Answer: (C) Both 1 and 2

In the standard school classification, mercury is the only metal found in the liquid state at room temperature, so statement 1 is correct. Bromine is the only liquid non-metal at room temperature, so statement 2 is correct. Both are common NCERT facts. The common error is to name gallium or cesium, which have melting points close to room temperature but are still solids under normal classroom conditions.
