Unit Objectives:
At the completion of this unit, students will be able to:
1. Draw and label the five major atomic models throughout history (Dalton, Thomson, Rutherford, Bohr, DeBroglie/Schrodinger).
2. State Dalton’s Atomic Theory and identify statements that we now know are inaccurate.
3. Identify the scientists (Thomson, Rutherford, Bohr) responsible for furthering the development of the modern atomic model and explain how their experiments led to their discoveries.
4. Define & identify isotopes and ions, including cations and anions.
5. Calculate the average atomic mass of an element.
6. Determine the number of subatomic particles in an isotope or ion based on the atomic number, mass number, and charge.
7. Convert between the number of particles, moles, or mass of a sample (the mole concept).
8. Write electron configurations of atoms (and ions) using orbital, dot, and exponential notation.
9. Explain the structure of the atom based on the modern atomic theory using the terms: principle energy level, sublevels, and orbitals.
10. Explain the principles of electromagnetic radiation, especially visible light.
11. Mathematically relate the amount of energy released by a photon to its frequency and/or wavelength
