There isn't one specific name for *all* the gases of the atmosphere together, but we often refer to it as air.

While "air" technically refers to the mixture of gases we breathe, it's commonly used to encompass all the gases in the atmosphere, including:

* Nitrogen (N2): Makes up the majority (about 78%) of the atmosphere.

* Oxygen (O2): Essential for life as we know it (about 21%).

* Argon (Ar): An inert gas (about 0.9%).

* Carbon dioxide (CO2): A greenhouse gas that plays a role in regulating Earth's temperature.

* Other trace gases: Including neon, helium, methane, krypton, hydrogen, and ozone.

So, while there's no single name for the complete collection of atmospheric gases, "air" is the most commonly used and understood term.
