The element chlorine is found in a gaseous state while bromine is found in:
Correct answer: B. Liquid state
- A. Solid state
- B. Liquid state
- C. Crystalline form
- D. Condensed form
Explanation
At room temperature and atmospheric pressure, chlorine (Cl2) is a yellow-green gas, while bromine (Br2) is a reddish-brown liquid. Bromine is one of the few elements that is liquid at room temperature.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
