Burning sodium isn't the only way to produce sodium oxide. Also, the article incorrectly said sodium oxide is formed by adding sodium bicarbonate to water, kind of the reverse of how you'd actually produce sodium oxide from sodium bicarbonate. —Preceding unsigned comment added by 74.232.9.203 (talk) 19:53, 18 September 2010 (UTC)

[edit]So sodium oxide and sodium monoxide are the same thing? — Preceding unsigned comment added by Chan81chan81 (talk • contribs) 09:21, 18 October 2016 (UTC)
Name
[edit] has
IUPAC Name: "disodium oxygen(2-)"

How is it made ?
[edit]So you can make sodium oxide by burning sodium in oxygen. Alrighty then, glass has been made for 3000 years. How did they make sodium oxide before the process for making sodium was invented? Eregli bob (talk) 15:09, 11 May 2010 (UTC)
- As it says, glass is made using sodium carbonate. The CO2 then comes out when it is molten. Gah4 (talk) 16:30, 10 October 2018 (UTC)
Unit Cell?
[edit]According to this, http://upload.wikimedia.org/wikipedia/commons/f/fd/Sodium-oxide-unit-cell-3D-balls-B.png there are 4 oxygen atoms in sodium oxide. So in a unit cell there are 4 oxygens. But when you look at the sodium, you have 1/8 an atom in each of the 8 corners, plus 1/2 an atom in each of the 6 faces. Thus you have 4 sodium atoms in a cell. So there are 4 sodium atoms and 4 oxygen atoms in a cell, even though the formula is Na2O? 173.167.163.13 (talk) 16:43, 3 May 2011 (UTC)
- Thanks for checking! You almost convinced me too. But there are eight Na's inside the cell. Your count of the atoms on the faces and corners is correct.
How can it both melt and sublime?
[edit]The infobox claims that the melting point is 1132 °C. Then the boiling point entry claims that it sublimes sic: "sublimates"; I mean, eww at 1950 °C, and the "sublimation conditions" entry says 1275 °C.
I suppose these things could all be true at different pressures, but no pressures are mentioned. At the very least this is hard to follow. Any help? --Trovatore (talk) 21:13, 13 March 2025 (UTC)
