Move to Helium hydride ion?

After a quick literature search, I'm left with the impression that helium hydride ion and helium hydride molecular ion are used much more often than hydrohelium ion. (Actually, the most common is HeH⁺, but I'd rather use words.) Should we rename the article?

Just thinking aloud, "hydride" suggests a H^- in there, which seems a bit strange. Is that what people really call it? --Rifleman 82 (talk) 09:47, 24 June 2008 (UTC)[reply]

That's exactly what I thought, but people do call it that way. I suppose the rationale is that the neutral molecule, HeH, is reasonably called helium hydride (unless you want to call it hydrogen heliide?), so this cation is the molecular ion (in the mass spectrometry sense) of helium hydride. --Itub (talk) 09:55, 24 June 2008 (UTC)[reply]

The rename sounds like a good idea. Use the most common term that's not an abbreviation. Graeme Bartlett (talk) 22:00, 24 June 2008 (UTC)[reply]

Incorrect image

The current image is misleading - HHe⁺ is isoelectronic with H₂, and therefore the two atoms in the cation should have identical size. Whoop whoop pull up ^{Bitching Betty | Averted crashes} 02:12, 28 December 2011 (UTC)[reply]

I doubt they are the same size. With a higher charge on the nucleus the He+ would be smaller. Graeme Bartlett (talk) 08:06, 3 May 2012 (UTC)[reply]

Then the image is still wrong, because it shows the He⁺ (cyan) larger than the H (silver). Double sharp (talk) 15:00, 30 May 2012 (UTC)[reply]
