Unit 2: Atomic Theory

Atomic Theory

UNIT Objective: Describe the key features of Atomic Theory and how it's changed over time.

Notes packet, Slides Presentation

• Atomic Structure

  • Objective: 

    • Describe the structure of atoms including protons, neutrons, electrons and their properties

    • Describe what is meant by ions, isotopes and use and interpret isotopic notation.

  • Activities

    • Atomic Structure Inquiry activity

    • Atomic Theory Basics notes

• History of the Atomic Model

  • Objective: Describe how our understanding of atoms has changed over time in terms of key experiments, observations and the resulting models.

  • Activities

    • Mystery Disk Activity

    • Atomic Model History Jigsaw Activity (experts get 1 model, home group puts them in order and match models to images)

• Atomic Mass

  • Objectives: 

    • Describe what is meant by atomic mass, determinant he quantity of subatomic particles given an isotopic notation and understand how weighted average atomic masses are calculated

    • Honors: Use data to calculate weighted average atomic masses.

    • PEEA# Practice

• The Bohr Model

  • Objectives:

    • Use and interpret Bohr models of the atom to determine subatomic particle quantities, electron configurations, and number of valence electrons.

  • Activity

    • Bohr Models Activity (get Bohr models, PEEA#, #n, electron configuration, sort by atomic number and chemical properties, make observations)

• Review

• Exam
