Elemental classification: Bromine is best described as which of the following at room temperature? Consider both physical state and its classification in the periodic table. Choose the correct description.

Difficulty: Easy

A non-metallic liquid (halogen)
A metal
A metalloid
A noble gas

Correct Answer: A non-metallic liquid (halogen)

Explanation:

What is being asked?
The physical state and class of bromine at room temperature.

Given data

Element group: Halogens (Group 17)

Concept/Approach
Bromine (Br₂) is a reddish-brown liquid non-metal at room temperature; among elements, only bromine and mercury are liquids near 25 °C (mercury is a metal).

Final Answer
A non-metallic liquid (halogen)
