11/13/16 Lecture Notes Chapter 10 continued ● Molecular Orbital Diagrams ○ To use MO diagrams for a given species, ■ Count the number of valence electrons ■ Add valence electrons to lowest energy MOs ○ Empty MO diagrams will be provided on exams; ignore AOs if present ○ For MOs only consider valence orbitals and electrons ● P orbital overlap ○ Can bond head-to head or side-to-side, antibonding or bonding in 4 different ways ● ● Magnetism ○ Paramagnetic​ species contain unpaired electron(s) and are attracted by external magnetic fields. ○ Diamagnetic​ species contain only paired electrons and are slightly repelled by a magne
