Talk:Hydrogen-4

1. Hydrogen
2. Deuterium
3. Tritium
4. How can this isotope be named in a way that parallels the others?? My guess is "quartium". Is this right?? (Please don't read too much into this question; I'm asking how it can be named in a way that parallels the others, NOT what name of this kind is in common use.) 66.245.28.46 03:30, 4 Dec 2004 (UTC)

Wrong, it goes: protium, dèutèrium, tritium, tètartium, pèntium, hècsium, èptium. Use the Cupròs dictionary. -lysdexia, 69.108.175.213 12:22, 4 September 2006 (UTC)

The above list was too Latinisede; here are the Hellènic stems: protium, deuterium, tritium, tetartium, pebtium/qentium, hectium, hevdòmium, ògdium, enatium, decatium. -lysdexia 11:55, 15 September 2007 (UTC)

I'd expect protium, deuterium, tritium, tetartium, pemptium, hektium, hebdomium, ogdoium, enatium, dekatium, hendekatium, dodekatium...

As a Greek speaker I have to agree with this one.

1. How can H-4 have that mass? Wouldn't it be 5?(Or ~5.0005 if you include the electron).

Reference inaccessible

The link from "this article" now leads to a Scitation website which not only requires a password, but does not even give the standard bibliographic information: authors, title, journal name, volume, pages, year. This means that it is impossible to check the information in the library of a university which does not subscribe specifically to Scitation.

Could someone please insert this information in the article for interested readers? Dirac66 (talk) 21:59, 15 November 2008 (UTC)

The answer to why:

  "1. How can H-4 have that mass? Wouldn't it be 5?(Or ~5.0005 if you include the electron)."

Hydrogen-1 has 1 proton and 0 neutron and an atomic mass near 1. Hydrogen-2 has 1 proton and 1 neutron and an atomic mass near 2. Hydrogen-3 has 1 proton and 2 neutron and an atomic mass near 3.

Why would hydrogen-4 have an atomic mass of 5?
