Sodium nitrate is the chemical compound with the formula Na N O 3 . This alkali metal nitrate salt is also known as Chile saltpeter (large deposits of which were historically mined in Chile ) [ 4 ] [ 5 ] to distinguish it from ordinary saltpeter, potassium nitrate .
Since metals can display multiple oxidation numbers, the exact definition of how many "valence electrons" an element should have in elemental form is somewhat arbitrary, but the following table lists the free electron densities given in Ashcroft and Mermin, which were calculated using the formula above based on reasonable assumptions about ...

The detonation velocity values presented here are typically for the highest practical density which maximizes achievable detonation velocity. [ 1 ] The velocity of detonation is an important indicator for overall energy and power of detonation, and in particular for the brisance or shattering effect of an explosive which is due to the ...
The standard Gibbs free energy of formation (G f °) of a compound is the change of Gibbs free energy that accompanies the formation of 1 mole of a substance in its standard state from its constituent elements in their standard states (the most stable form of the element at 1 bar of pressure and the specified temperature, usually 298.15 K or 25 °C).
That value is also the standard formation energy (∆G f °) for an Fe 2+ ion, since e − and Fe(s) both have zero formation energy. Data from different sources may cause table inconsistencies.
The least stable, LiNO 3 (m.p. 255 °C (491 °F)) decomposes only at 474 °C (885 °F). At the other extreme, cesium nitrate melts at 414 °C (777 °F) and decomposes at 584 °C. [2] 60:40 mixture of sodium nitrate and potassium nitrate is a liquid between 260–550 °C (500–1,022 °F).
