Question

Quizplus · Accepted Answer

Argon is a noble gas with a full valence electron shell, making it unreactive. The only other noble gas in the answer choices is krypton (Kr), which is expected to have similar chemical and physical properties to argon. The other elements in the answer choices are not noble gases and have different numbers of valence electrons, so they are not expected to have properties similar to argon.
