Move the main image to the phase section and replace it with a new one.[edit]
The current main image is hydrogen in its plasma state, but it would make more sense to move that to Hydrogen#Phases. Then replace it with a new better image. Bennett27 (talk) 01:54, 11 February 2024 (UTC)[reply]
There is a move discussion in progress on Talk:Hydrogen economy which affects this page. Please participate on that page and not in this talk page section. Thank you. —RMCD bot 07:33, 19 February 2024 (UTC)[reply]
Inaccurate to say hydrogen is "explosive" at 4% to 74% in air. This is its flammability range.[edit]
This should be amended in the first paragraphs of the "properties" section. Saying it is explosive at 4% gives a false impression about its risks, and feeds into a common misconception that flammability limit = detonation limit. Indeed, citation [21] refers to flammability range, and does not appear to mention explosive mixtures.51.194.9.191 (talk) 13:33, 28 February 2024 (UTC)[reply]
