Description: Structure of atoms, ions, and molecules; periodic table; basic notation; and states of matter. Includes topics on bonding and the electrical conductivity of materials using hole and electron flow.
Length of time: 5 hrs.
1. Atomic structure
2. Atoms or Elements
5. The Periodic Table (Chart)
7. Electrical conduction
8. States of matter
9. Basic notation (e.g. H2O)
Students will be able to:
1. Use sketches to describe an atom, ion, and molecule.
2. Draw and identify the parts of an atom. Provide sketches to describe the atomic structure of a given atom , e.g. carbon, germanium, and silicon.
3. Discuss four states of matter. Include plasma.
4. Describe the Periodic Table and show an example of its use. Using the table, give an example of a symbol for an atom, its atomic number, and atomic weight.
5. Use the Periodic Table, identify the materials used for doping.
6. Locate semiconductor materials and some good conductors on the Periodic Table. Note their locations on the Table.
7. Explain what is meant by bonding. Give examples of types of bonding.
8. Show the similarities and differences between molecules, compounds, and mixtures.
9. Explain electrical conduction from the standpoint of atomic theory. Compare and contrast hole conduction with electron conduction.
