💡 Analysis & Explanation
Elemental Properties ▼
Elements are classified into metals, non-metals, and metalloids based on physical and chemical traits. Most non-metals exist in gaseous states (e.g., Nitrogen, Oxygen) or brittle solid states (e.g., Carbon, Sulfur) under standard conditions.
The Chemical Exception ▼
Bromine (atomic number 35) is an extreme outlier in the halogen group. It is the only non-metallic element in the entire periodic table that exists naturally as a heavy, reddish-brown, fuming liquid at standard room temperature.
Eliminating Others ▼
Mercury and Gallium are metals (though Mercury is liquid, it is NOT a non-metal). Chlorine is a gas.
Conclusion ▼
Bromine is the accurate chemical answer.
