This
page is even more confusing than the Chemical page, eh? I
think so too, so let's clarify a few things. The three bottom
ones under the temperatures section I have no clue about.
The Single Bond Enthalpies part means Neon bonding with another
element, like Neon bonding with Fluorine is not applicable.
Don't even ask me what the four bottom ones under Thermodynamic
Properties mean, or under Crystal structure. Otherwise, everything
else is self explanatory.
