Question

What description most accurately characterizes argon?
A. Argon is a halogen and displays remarkable reactivity as it possesses a partially filled valence shell.
B. Argon, classified as a noble gas, demonstrates significant reactivity due to its complete valence shell.
C. Argon, being a noble gas, displays remarkable unreactivity due to its complete valence shell.
D.Argon is a halogen and exhibits high unreactivity owing to its partially filled valence shell.

Answer 1

The description that most accurately characterizes argon is:

C. Argon, being a noble gas, displays remarkable unreactivity due to its complete valence shell.

Argon is a noble gas, which means it has a full outer electron shell, resulting in very low reactivity compared to other elements.
