Document Summary

Specific atom is defined by z, with its atomic mass being the weighted avg of all natural isotopes. Orbitals define where an electron would be 90-95% of the time this is rep"d by a cloud: four: spdf with p having three different shells: px , py , pz each sep"d by a node. Convention for 2d representation of 3d atoms: solid line = bond in plane of page, wedge = bond coming out to the viewer, dashed = bond goes away from viewer. Atoms bond because resulting compound is more stable: making bonds = release energy ; Kekule structures are line-bond structures where a single bond is replaced by a solid line. Sulfur, oxygen, and phosphorus follow the same concepts with hybridization. Know how to draw chemical structures properly: full, condensed, skeletal, and 3d forms hybridization is needed for 3d forms. Chapter 2: polar covalent bonds; acids and bases.
