In[1]:= Needs[Miscellaneous`ChemicalElements`]

In[2]:= Names[Miscellaneous`ChemicalElements`A*]
Out[2]= {Abbreviation, Actinium, Aluminium, Aluminum, Americium,  
  Antimony, Argon, Arsenic, Astatine, AtomicNumber, AtomicWeight}

In[3]:= Information[Miscellaneous`ChemicalElements`Argon]

Argon is a chemical element.
Abbreviation[Argon] ^= "Ar"
 
AtomicNumber[Argon] ^= 18
 
AtomicWeight[Argon] ^= 39.948
 
BoilingPoint[Argon] ^= 87.3*Kelvin
 
Density[Argon] ^:= 
 
  Miscellaneous`ChemicalElements`Private`DensityException[
 
   Argon, 1655.999999999999, 40]
 
ElectronConfiguration[Argon] ^= {{2}, {2, 6}, {2, 6}}
 
HeatOfFusion[Argon] ^= (1.209999999999999*Joule*Kilo)/Mole
 
HeatOfVaporization[Argon] ^= (6.53*Joule*Kilo)/Mole
 
MeltingPoint[Argon] ^= 83.79999999999999*Kelvin
 
StableIsotopes[Argon] ^= {36, 38, 40}
 
ThermalConductivity[Argon] ^:= 
 
  Miscellaneous`ChemicalElements`Private`ThermalConductivityException[
		Argon, 0.01772, "gaseous"]
