Questions & Answers about Der Atem ist ruhig.
Because Atem is a masculine noun in German. Its dictionary form is der Atem.

A useful habit is to learn German nouns with their article, not by themselves.
In normal German, singular countable nouns usually need an article or some other determiner.
So:
- Der Atem ist ruhig. = natural, normal German
- Atem ist ruhig. = sounds incomplete or unusual in standard German
German uses articles more regularly than English in many cases, so even when English might be more flexible, German often still wants der / die / das.
Atem means breath.
In a sentence like this, it usually refers to a person’s breathing as it is being observed at that moment:
- Der Atem ist ruhig. = the breath is calm / the breathing is calm and steady
