The noble gases are placed in a separate group because they have unique chemical and physical properties that make them distinct from the other elements in the periodic table. They are all monatomic (single atom) gases with extremely low reactivity, and they are all colorless, odorless, and tasteless. These characteristics make them particularly well-suited for a wide range of industrial, scientific, and medical applications.

The noble gases are placed in a separate group cause of their low reactivity when compared to other group elements. The noble gas occurs in lower concentrations in the atmosphere. These elements do not combine with other elements in the periodic table except the element "Xenon"
