* Inert gases: This term is outdated, as some noble gases have been shown to participate in chemical reactions.

* Rare gases: While they are relatively rare in the atmosphere, they are not actually rare in the universe.

* Group 18 elements: This is their official IUPAC group designation.

Here's a table comparing the different names:

| Name | Description |

|---|---|

| Noble gases | The most common name, reflecting their low reactivity. |

| Inert gases | Outdated, as some noble gases do react. |

| Rare gases | While relatively rare in the atmosphere, they are not actually rare in the universe. |

| Group 18 elements | The official IUPAC group designation. |
