Document Summary
Chapter 7: the quantum-mechanical model of the atom. Before 20th century, descriptions of the behavior of matter had been deterministic (present set of conditions completely determining the future). Early 20th century brought changes that revolutionized how we think about physical reality. New theory suggest that for subatomic particles (electrons, neutrons, and protons) do not completely determine the future. Ex- electrons traveling down a path under the same conditions do not land in the same place. Quantum mechanical theory developed by einstein, bohr, broglie, planck, heisenberg, dirag, and. Schrodinger, all of them not comfortable with own theory. Quantum mechanics is able to account for fundamental observations including the stability of atoms (not understood within framework of classical physics) Quantum mechanics form the foundation of chemistry- explaining periodic table and the behavior of the elements in chemical bonding and providing the practice basis for lasers, computers, and other applications. An atom"s electron determine many of its chemical and physical properties.
