The electronic configuration of Ar is 1s2 2s2 2p6 3s2 3p6. Because the third energy level has eight electrons (full), it is called a Nobel Gas. As listed in Table 3217, substances with large bonding energies usually have high melting temperatures. Table 3217. Bonding energies and melting temperatures of van der Waals bonding-type substances.
Argon contents are often detected in EM (TEM or SEM) samples in the two cases: In electron microscopes, both EELS and EDS techniques can normally be used to detect argon contents in materials.
