Pluchino – Regents Chemistry Atomic History & Electron Configuration – 04 Intro to Quantum Mechanics Aim: What model of the atom is used today? Do Now: The Bohr model only works for hydrogen, why? Quantum Mechanical Wave Model Electrons have characteristics of both particles and waves Based on the probability of the presence of an electron in a given area (electron cloud) Developed with high level mathematics Heisenberg Uncertainty Principle: We cannot simultaneously determine the momentum and position of an electron Every electron in an atom has 4 values that correspond to its location and energy… Energy level Sublevel Orbital Spin Borough Street Building Apartment # Principle Energy Level: Indicates the distance an electron is from the nucleus and describes the size of the electron cloud (always a whole number) Sublevel: Describes the general shape of the electron cloud. Number of sublevels is dictated by the principle energy level Orbitals:
