1 year agoSmall addition: I wouldn’t call O3 (Ozone) charged. It “only” has some partial charge like water (H2O) does, but overall it has the same number of protons and electrons.
Now you could have ozonide (O3-), but that’s definitely a way more rare case.
As we are assumed to get enough oxygen no matter what, I think blood thinners to stop us from dying of a stroke would be fair game too.
