What are three characteristics of noble gases?

Answer 1

Noble gases are gases and have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.

Answer 2

Noble gases are all monatomic (single-atom molecules) and have the following characteristics under normal conditions :

1. Odorless
2. Colorless
3. Low reactivity (due to a full outer electron shell)

Answer 3

Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2 valence electrons) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.

Answer 4

Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.

Answer 5

1. Noble gases are inert and unreactive, meaning they rarely form chemical bonds with other elements.
2. They are colorless, odorless, and tasteless gases at room temperature.
3. Noble gases have a filled outer electron shell, making them stable and non-reactive.

Answer 6

They are "unreactive" as their outer electron shells are full and thus will not donate or accept electrons readily.
