Some Dimers of Triatomic Radicals with 17 and 19 Valence-Shell Electrons, illustrate aspects of qualitative valence-bond and molecular orbital theory for electron-rich polyatomic molecules, and in particular, interconnections between these theories can be demonstrated.

Transition Metal Complexes with CO, N2, NO and O2 Ligands, have triple bonds and no unpaired electrons in their Lewis octet structures (1)–(3). Each may use a lone-pair of electrons to coordinate with a transition metal, as in (4)–(6), thereby functioning initially as Lewis bases. NO and O., with 11 and 12 valence-shell electrons respectively, have one and作者: 移動 時間: 2025-3-24 06:41

Finally, by making particular use of the charge distribution for antibonding orbitals, expressions for atomic valencies will be deduced for “increased-valence” structures.作者: Capitulate 時間: 2025-3-26 01:44

Classical Valence Structures and Quinquevalent Nitrogen Atoms,e” structure is sometimes used to represent their electronic structures. Since the 1860’s and up until the introduction of the Lewis-Langmuir octet theory, nitrogen atoms were very often represented with valencies of 3 or 5 in valence-bond structures. For example, valence-bond structures for N.O, Me.NO, and N.O. were written as (1)-(3).作者: 幼稚 時間: 2025-3-28 01:57 作者: Accede 時間: 2025-3-28 02:18 作者: 跳動 時間: 2025-3-28 08:29 作者: NICHE 時間: 2025-3-28 14:10
