Unit 2: Atomic Structure
Tentative Timeline: 3 weeks
Chapters 4 and 5
LEARNING GOALS:
● Identify the key theories in the evolution of the atomic theory (Democritus, Dalton, Thomson, Rutherford, Bohr and quantum model)
● Differentiate between the 3 sub atomic particles, their charge and location in the atom
● Describe and interpret the number of subatomic particles in an atom given particular information (neutral atom/isotopes/ions)
● Explain what distinguishes and differentiates one atom of an element from another, and atoms of different isotopes.
● Calculate average atomic mass given isotope data
● Describe and calculate the relationship between the wavelength and frequency of light and energy
● Identify types of spectra (line, band, continuous)
● Write full and abbreviated electron configurations
- Describe the orbital filling principles (Aufbau, Pauli, Hund’s, and Heisenberg)
Essential Vocabulary:
● atom

● atomic number
● Dalton’s atomic theory
● electron
● isotopes
● mass number
