• • Chapters in Book: Chp 4 and 9

    • Students will be able to...

      • 9. Explain and apply subatomic particles to the periodic table based on the historical development of atomic theory and how this relates to trends observed.

        • Can identify the subatomic particles (electrons, protons, and neutrons) that make up the atom and identify their charge, location, and mass.

        • Can define the following terms: Atom-Atomic number-Atomic mass.

        • Can complete a table showing my understanding of relationship between protons, neutrons and electrons in an atom.

        • Can define ion and isotope, and discuss differences of subatomic particles.

        • can determine the charge on an ion

        • can outline the development of the model of the atom by identifying scientists and their contributions to our understanding of the atom.

        • Can explain conclusions of the cathode ray tube and gold-foil experiments.

        • Alkali metals, Alkali Earth, Halogens and noble gases

        • Metals, nonmetals and metalloids

        • Predict ionization energy, electronegativity and atomic radius, ionic radius based on the trends from the periodic table.
