Q. Which of the following is a non metal that remains liquid at room temperature?

  • (A) Phosphorus
  • (B) Bromine
  • (C) Chlorine
  • (D) Helium
Explanation by: Admin

Bromine is a non-metal that remains in a liquid state at room temperature (around 20°C or 68°F).

  • Phosphorus: Exists as a solid at room temperature (white phosphorus is solid).
  • Chlorine: Exists as a gas at room temperature.
  • Helium: Exists as a gas at room temperature, and it only becomes a liquid at extremely low temperatures.

So, Bromine is the only non-metal that remains liquid at room temperature.
