What gases have similar features as neon?

Gases that have similar features to neon include other noble gases like argon, krypton, xenon, and radon. These gases are all colorless, odorless, and non-reactive under standard conditions due to their complete valence electron shells. Like neon, they exhibit low chemical reactivity and are found in trace amounts in the Earth's atmosphere. Additionally, they share similar physical properties, such as being gases at room temperature and having low boiling points.
