This book (Practical Electron Microscopy and Database) is a reference for TEM and SEM students, operators, engineers, technicians, managers, and researchers.


As listed in Table 3218, substances with large bonding energies usually have high melting temperatures.

Table 3218. Bonding energies and melting temperatures of van der Waals bonding-type substances.

Bonding type

Bonding energy
Melting point (°C)
kJ/mol kcal/mol eV/Atom, Ion, or Molecule
van der Waals
Typical value 0.1-10      
Ar 7.7 1.8 0.08 -189
Cl2 31 7.4 0.32 -101

Note that page3239 describes the correlation between the bonding energies and melting temperatures of different substances.
