Which of the following are considered noble gases?

A. Bromine

B. Neon

C. Argon

D. Chlorine

From the given options, Neon and Argon are considered as noble gases.

Answer: Options B and C

Explanation:

All elements present in the Group Zero usually considered as noble gases. Also referred as rare or inert gases. Because researchers trusted that they are incapable to react with all other elements.

The elements are neon (Ne), helium, radon (Rn), xenon (Xe), krypton (Kr), and argon (Ar). Argon and Neon are the elements that have atoms with eight electrons in their outermost orbits.

Hence, they don't interact or react with other existing elements and are considered as noble gases, existing in the gaseous state of matter.

Neon and argon because both are group 8 atoms so they are entirely stable and noble.
