Which of the following is **not** a noble gas?
AArgon
BKrypton
CBromine
DXenon
Answer & Solution
Correct answer: C. Bromine
Noble gases (group 18): He, Ne, Ar, Kr, Xe, Rn, Og. All chemically inert in their natural state (Xe and Kr can form a few compounds under extreme conditions).
**Bromine** is a halogen (group 17), not a noble gas. It's a reactive non-metal, liquid at room temperature, deep red-brown.
