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)
Infrastructure
[edit]I would welcome your thoughts at Talk:Hydrogen infrastructure#Merge sub-topics into here Chidgk1 (talk) 18:00, 13 February 2024 (UTC)
Move discussion in progress
[edit]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)
Inaccurate to say hydrogen is "explosive" at 4% to 74% in air. This is its flammability range.
[edit]Hydrogen's explosivity is listed here as 4% to 74% in air. It's more accurate to say its limit of detonability is 18% to 59%. See, for example, https://www1.eere.energy.gov/hydrogenandfuelcells/pdfs/h2_safety_fsheet.pdf, or https://en.wikipedia.org/wiki/Hydrogen_safety "inerting and purging
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)
Mention the routes of the word Hydrogen
[edit]Mention the routes of the word hydrogen (Hydro) from Ancient Greek: ὕδωρ, romanized: hýdōr, lit. 'water' (water) as well what caused the discoverer came up with the respective name reference (Gen) from Ancient Greek: γένος, 'birth' (meaning formation) Clearly showing the processes and reasoning of the making of the word (Water being composed of Hydrogen and Oxygen) Athan Kokkinos (talk) 04:36, 6 August 2024 (UTC)
- You probably mean "roots", not "routes". The English term for word origins is "etymology". Hydrogen can be thought of as meaning "water generator" or "water origin" which is accurate in the context of burning elemental hydrogen and oxygen (2H2 + O2) produces water.71.31.145.237 (talk) 15:13, 7 August 2024 (UTC)
Where are the molecular properties?
[edit]I figured certainly either this article would have the H-H bond distance in H2, or it would link to molecular hydrogen article. The fact that it does neither is quite disappointing.
- Also I see an illustration of a spherical H atom and a cutout depicting the proton. This is really unfortunate. It should be removed. Reasons:#1 The Bohr Model is OBSOLETE, it does our readers a disservice to mention it here.#2 The sphere shows a definite surface which is misleading. The reason why the electron cloud is called a 'cloud' is because it HAS no distinct surface. #3 The surface is some UNSPECIFIED cumulative electron (charge) probability and is mostly arbitrary. Is it any more useful if it's the 80% surface? the 90%? 95%? 99%?, 99.9%? There's nothing special about the arbitrary 1.1 Angstrom diameter. #4 Atoms radii, not diameter, appears far more frequently in the chemical literature. #5 Juxtapositioning the spherical "atom" diameter in the same illustration as the much, much, much, much, much smaller proton (it can't even be shown at the same scale and that should be a good hint!) is not useful. Why not just use numbers? H radius 550 pm, proton radius 0.00085 pm (along with a note that atomic scale (and smaller) sizes strongly depend on the method, the probe, used to measure them.) 71.31.145.237 (talk) 15:46, 7 August 2024 (UTC)
