Talk:Hydration number

The section (and figure) about methane hydrate is out of place. Hydration number is not about clathrates. The hydration of protons should be discussed and depicted. And most of all, metal cations, including all sorts of cations (vanadyl, alkali metal cations, lanthanides), showing the first coordination sphere.--Smokefoot (talk) 01:28, 8 July 2023 (UTC)
