Where it comes from
The claim comes from Royal Society of Chemistry, and the page it comes from was read on 2026-08-27 to confirm it still says this.
This is not the kind of claim that goes out of date, which is why it was set as a puzzle rather than a fact with a shelf life.
The sentence itself was written for this site rather than quoted from anywhere, so what you are solving is our wording of a claim that is somebody else’s. The explanation is on the answer page.
Want the answer?
Have a proper go at it first. The solution is on a page of its own, so you won’t run into it by accident.
