9 - Chapter 1 Student Outcomes Students will be expected to: Demonstrate knowledge of WHMIS standards by using proper techniques for handling and disposing of lab materials. - define WHMIS identify each of the WHMIS symbols use a Materials Safety Data Sheet (MSDS) to obtain required safety information Compare earlier conceptions of the structure of matter with current conceptions. - define matter define atom Investigate matter and describe it in terms of its physical properties and chemical properties. - - distinguish between physical properties and chemical properties list and define examples of physical properties: colour malleability electrical conductivity magnetism luster density melting/boiling points texture list and define examples of chemical properties: combustibility reactivity Explain the importance of using the terms law and theory in science. - distinguish between a theory and a law Identify major changes in atomic theory up to and including the Bohr model. - describe the contributions of Empedocles, Democritus, and Aristotle describe the contribution of Dalton list the set of ideas that made up Dalton’s atomic theory describe the contribution of Thompson describe the contribution of Rutherford describe the contribution of Bohr Describe Rutherford’s experiment to test Thomson’s atomic model as an example of how technologies have enhanced, promoted, or made possible scientific research in chemistry. - recognize that the atomic theory continues to be refined Use models in describing the structure and components of atoms. - distinguish among protons, neutrons, and electrons in terms of their: charge relative mass location in the atom Proton Electron Neutron Charge Positive (+) Negative (-) No charge Relative Mass 1836 (1 unit) 1 (insignificant) 1837 (1 unit) Location in the Atom Nucleus Surrounding the Nucleus Nucleus Provide examples to illustrate that scientific and technological activities related to atomic structure take place in a variety of individual and group settings.
