Answer: The answer is B. low or no reactivity.
Explanation: Neon and argon are both noble gases, which means that they have a full outer electron shell and are therefore very stable. This makes them very unreactive, meaning that they do not easily form bonds with other elements.
The other answer choices are incorrect:
Neon and argon are both colorless gases, so they do not have a silver color.
Neon and argon do not have a metallic texture.
Noble gases do not have a strong odor.
Therefore, the most likely property that neon and argon share is low or no reactivity.
