Document Summary
Quantum mechanics - the fundamental branch of physics that describes the properties, interactions, and motions of atomic and subatomic particles used to explain the redistribution of electrons that forms chemical bonds. Electronegativity - the tendency of an atom in a molecule to attract electrons from other atoms chemical bond explains whether a given pair of atoms form an ionic, covalent, or polar covalent bond. Classical theory of bonding - using electrostatics to understand conceptual models of uses lewis dot diagrams and vsepr (valence shell electron-pair repulsion) theory. Molecule - a collection of atoms bonded together. Isomers - different compounds that have the same molecular formulas, but differ in molecular molecules structures and compounds. *properties of compounds are determined by the structures of their molecules* Periodic law - the chemical properties of the elements are periodic functions of the atomic number z (z is increasing atomic number)
