Electron configuration stable

Closed-shell electron configuration Stable electron configuration in which all the lowest energy orbitals of an atom (in the case of the noble gases), an ion (e.g., Na ), or a molecule (e.g., benzene) are filled. 

Simple stable carbonyls, except V(CO)o, have an electronic configuration corresponding to the next noble gas. Carbonyl groups can be substituted by other unchanged ligands (e.g. 

Krypton is found to be an extremely unreactive element indicating that it has a stable electronic configuration despite the fact that the n = 4 quantum le el can accommodate 24 more electrons in the d and / orbitals. 

Loss of one electron gives the noble gas configuration the very large difference between the first and second ionisation energies implies that an outer electronic configuration of a noble gas is indeed very stable. 

In the older form of the periodic table, chromium was placed in Group VI, and there are some similarities to the chemistry of this group (Chapter 10). The outer electron configuration, 3d 4s. indicates the stability of the half-filled d level. 3d 4s being more stable than the expected 3d 4s for the free atom. Like vanadium and titanium, chromium can lose all its outer electrons, giving chromium)VI) however, the latter is strongly oxidising and is... 

The covalent, or shared electron pair, model of chemical bonding was first suggested by G N Lewis of the University of California m 1916 Lewis proposed that a sharing of two electrons by two hydrogen atoms permits each one to have a stable closed shell electron configuration analogous to helium... 

Covalent bonding in F2 gives each fluonne eight electrons in its valence shell and a stable electron configuration equivalent to that of the noble gas neon... 

FIGURE 2 8 sp Hybridization (a) Electron configuration of carbon in its most stable state (b) Mixing the s orbital with the three p orbitals generates four sp hybrid orbitals The four sp hybrid orbitals are of equal energy therefore the four valence electrons are distributed evenly among them The axes of the four sp orbitals are directed toward the corners of a tetrahedron...
