Sodium , minimum metal-oxygen

The commercial product is a powder containing a minimum of 96% Na202 and approximately 20% active oxygen. It is made commercially by oxidizing the molten metal with either oxygen or air enriched in oxygen. Early industrial history (1) and manufacturing details (3) are available. Sodium... 

Figure 8.15 Comparison of radial distributions of oxygen atoms conditional on the simplest metal ions in typical aqueous solutions obtained by ab initio molecular dynamics (AIMD). See Asthagiri etal. (2004c) for details. The potassium result was presented by itself in higher detail in Fig. 7.7, p. 157. Notice that the lithium result (displaced vertically by 2) and the sodium result (displaced vertically by 1) have inner shells clearly defined on the basis of the g r). For lithium, the occupancy of that inner shell is almost exclusively 4. For sodium, the principal occupancy is 4, but there is a statistical admixture of another oxygen that also serves to blur the primary minimum this occupancy is indicated by 4-1. For potassium, this statistical characterization is 4 - 2, as was also shown differently by Fig. 7.7 this leads to the occultation of the principal minimum in that case.
