negative ions
Atoms with extra electrons
Negative ions are atoms or molecules that have gained one or more electrons, giving them a net negative electrical charge.
In scientific contexts, they're called anions and play essential roles in chemistry and biology.
In popular wellness culture, negative ions are promoted as health-enhancing—supposedly abundant near waterfalls, oceans, and forests—though scientific support for these claims is limited.
The air purifier claims to release negative ions.
