Unit 2: Atomic Structure

Unit Objectives: At the completion of this Atomic Structure unit,

1.  I can describe how atomic models have changed over time as new experimental results (due to Dalton, Thomson, Rutherford, Bohr, & Schrodinger) have led to new theories about the structure of the atom. (CK12 Sections 4.1, 4.6, 4.8, 4.13, 4.14, 5.6, 5.11)

2. I can determine the number of subatomic particles in an isotope or ion (cation/anion) based on the atomic number, mass number, and charge. (CK12 Sections 4.16, 4.17, 4.18, 6.16)

3. I can calculate the average atomic mass of an element. (CK12 Section 4.20)

4. I can convert between the number of particles, moles, or mass of a sample (the mole concept). (CK12 Sections 10.1, 10.2, 10.3, 10.4, 10.5)

5. I can explain the structure of the atom based on the modern atomic theory using the terms: principle energy level, sublevels, and orbitals. (CK12 Sections 5.12, 5.13)

6. I can write electron configurations of atoms and ions using orbital, dot, and exponential notation. (CK12 Sections 5.15, 5.17, 5.18, 8.1) 

7. I can explain how the ground and excited states of electrons influence the type of electromagnetic radiation emitted, especially visible light. (CK12 Sections 5.1, 5.5)

8. I can mathematically relate the amount of energy released by a photon to its frequency and/or wavelength. (CK12 Sections 5.2, 5.3)
