Talk:Lead dioxide

A fact from Lead dioxide appeared on Wikipedia's Main Page in the Did you know column on 10 June 2010 (check views). The text of the entry was as follows:

Did you know... that the name of mineral scrutinyite reflects the efforts spent to distinguish it from plattnerite – another form of lead dioxide?

Article name

Please discuss any concerns about the article name here. Vsmith (talk) 01:44, 7 April 2010 (UTC)[reply]

I have a problem with this name is because this chemical is an ionic compound not a molecular compound. The prefix "di" shouldn't be used to name ionic compound. Plus, the ion lead has multiple charges. The correct name should be "Lead(IV) Oxide" I use the roman numeral (IV) means that the lead ion has a +4 charge. --Flushing258 (talk) 03:05, 13 April 2010 (UTC)[reply]

A few points:

You have not given a reliable source that says PbO₂ is ionic — it may seem obvious from school-level chemistry, where you think of most inorganic compounds as ionic, i.e. [Pb⁴⁺][O²⁻]₂, but this a gross simplification. See
separation of charge in PbO₂, but in general I believe the greater the formal charge on the ion (i.e. especially pronounced with a formal tetracation like Pb⁴⁺), the less likely it is to find fully ionic bonding. The energy required to ionise Pb to Pb⁴⁺ and 2O to 2O²⁻ probably cannot be compensated for by the energy gained
from forming Pb⁴⁺···O²⁻ ionic bonds. Structure determinations:

Solid State Sciences (2005) 7, 1363–1368: High-pressure synthesis of α-PbO₂ and its crystal structure at 293, 203, and 113 K from single crystal diffraction data.
J. Alloys Compd. (2004) 377, 17–20: Hydrothermal crystal growth of the high-pressure phases of α-PbO₂ and TiO₂ II.
J. Phys.: Condens. Matter (1996) 8, 1631–1646: The high-pressure phase transition sequence from the rutile-type through to the cotunnite-type structure in PbO₂.
Solid State Commun. (2000) 115, 423–426: Transport properties of bismuth-doped β-lead dioxide.
Mater. Res. Bull. (1982) 17, 769–784: The crystal structures of lead dioxides from the positive plate of the lead/acid battery.
Acta Cryst. (1980). B36, 2394–2397: Powder neutron diffraction study of chemically prepared β-lead dioxide.

You have not given a reliable source to suggest that "lead dioxide" is an inappropriate name for an ionic compound.

Lead(IV) means Pb is in the +4 oxidation state, which is not exactly the same thing as saying lead has a +4 charge. "Lead(IV) oxide" would be an acceptable name for PbO₂, but it is not necessarily preferable to "lead dioxide", and "lead dioxide" is certainly not wrong.

Only the first letter of article titles is capitalised, so it would be "Lead(IV) oxide", not Lead(IV) Oxide".

For these reasons, I oppose any move to Lead(IV) Oxide.

Anhydrous plumbic acid

I've never heard this name used but I suppose it is analagous to Chromium trioxide and Chromic acid. Biscuittin (talk) 19:02, 23 November 2014 (UTC)[reply]
