Atomic and Molecular Electronic Configuration Revisited

In AMEC, chapter one, you will find a structure for O2 supported by both bond order and unpaired electron data. Previous attempts at providing an electronic structure for O2 fails due to bond order, number of unpaired electrons, or oxygen atoms indicating five orbitals although four is the limit. Herein, you will find the newly described 'LONE P ORBITAL Pi BOND' which is the solution not only for O2 but also for NO and OF (uncharacterized?). The 'LPOP' bond system is possible due to the small size and high electronegative character of the N, O and F atoms, which makes it related to H-Bonding. Diatomic structures involving row two periodic table elements (LiBe, Be2, BeB, B2, BC, C2, CN, N2, and F2) are also presented. All structures are shown being formed by two methods: MRAE (Most Recently Added Electron) and LCAO (Linear Combination of Atomic Orbitals). Chapter one also includes a (Section III) MRAE Mechanistic Sequence For: NO+ > NO > O2 > OF > F2 (and F2 > F- + F0), (Section IV) Photographs of NO and O2 molecular models, (Section V) MRAE-MO Energy Level diagrams for the diatomic structures listed above, and (Section VI) a MRAE-MO Energy-Level Diagrams Template, which is based on the cascade of changes in electronic distribution when an electron is forced onto a previous structure (MRAE), such as N2 going to N2 - and NO+ going to NO. Chapter 2 includes sections on hybridization and mechanism as it relates to polyatomic species. The following sequences are given: C + H > CH + H > CH2 + H > CH3 + H > CH4 (saturated and tetrahedral arrangement) and N + H > NH + H > NH2 + H > NH3 + H > NH4+ (also saturated and tetrahedral arrangement). The emphasis is to show trend from atomic structure through sp, sp2 and sp3 hybridization. Chapter 3 is composed of selections from Atomic and Molecular Configuration, 1987. Included is 'MRAE-AUFBAU' TEMPLATE' of the (periodic table) elements (expanded to two pages). It is informative to compare the MRAE concept for atoms to the MRAE method for diatomic species in Chapter one. In both cases, the key is the changes in electronic structure when an electron is added.

About the Author
The author, Harold "Mack" Teague was born and reared in the Massey Hill community of Fayetteville, North Carolina. He received his undergraduate degree from Methodist University (Fayetteville, NC) and Masters Degree (minor in inorganic/physical chemistry) and PhD degree (minor in biochemistry) in organic chemistry from North Carolina State University, Raleigh, NC. Currently, he is professor emeritus, UNC-Pembroke and teaches, if called upon. In addition to his chemistry he is active researching the relationship between cholesterol and diet. He began teaching at UNC-Pembroke in 1970, concentrating on general and organic chemistry, but also has taught biochemistry. In addition to teaching, he was and is active in chemical education. He has developed numerous interactive models constructed from simple materials such as Easter eggs. These interactive models were demonstrated at numerous chemical meetings and workshops. He received a US Patent, Assembly System for Demonstrating Chemical Structures (Teague, No. 5,110,297, May 5, 1992). His major goal in teaching is to make chemistry as simple as possible to comprehend. He co-authored, with Henry A. Bent, NCSU, a 'cover' article: The Hydro-Thermal-Dynamical Duck, A Sketch of his Uses in the Classroom and Laboratory, Vol. VIII, Sept. 1978, pp. 18-27. He received the University of North Carolina Board of Governor's Excellence in Teaching Award (Pembroke campus) for 1997. His greatest satisfaction, however, is the feedback from former students, colleagues and high school teachers, who attended his workshops.
