    Pacing Worksheet, Basic Atomic Structure
    Bundle Description

    7 days worth of live lessons, activities, and formative assessment!

    PLUS, a FREE pacing worksheet (Excel)!

    This is a collection of student-facing PowerPoint files containing all relevant notes, activities, and formative assessment for lessons describing the following:

    • contributions to modern atomic theory by Democritus, Dalton, Thomson, Millikan, Rutherford, and Chadwick
    • subatomic particles and their position within an atom
    • characteristic features of atoms, such as atomic number and mass number
    • electrically-neutral atoms
    • isotopes, concept and exploration
    • average atomic mass, prediction and calculation

    In this unit bundle, there are no lessons related to the Bohr or Schrodinger atoms. Electron organization and behavior is presented and sold as a separate unit bundle.

    Supplementary resources in the notes area include links to relevant web videos, manipulative activities like simulations, Quizizz, and Quizlet teacher links. The digital file and the links to supplementary resources can be further modified by the user.

    Each lesson in the bundle has been designed to be delivered within a 50-minute class period. They include direct instruction, modeled and small group practice, formative assessment, and next steps.

    Objectives, as listed in the slides, include the following:

    • List three people whose contributions to modern atomic theory were noteworthy.
    • Describe the ideas and discoveries each of these individuals made.
    • Appreciate the effort that goes into making BIG scientific discoveries.
    • Describe the ideas and discoveries of Rutherford and Chadwick toward our understanding of the modern atomic model.
    • Identify and describe the particles within an atom.
    • Determine the number of protons and electrons needed for an atom to be “electrically-neutral”.
    • Compare and contrast the chemical and physical properties of atoms and element samples.
    • Identify and recognize the importance of the “atomic number” for various atoms.
    • Use the atomic number and mass number of an atom to determine the number of particles in an atom.
    • Identify the difference in atomic structure between isotopes of the same element.
    • Use proper names and symbols to describe different isotopes.
    • Determine the number of particles in any isotope when given the name or symbol.
    • Practice the scientific method.
    • Create isotopes by manipulating the number of particles in an atom.
    • Observe how the average atomic mass changes with the relative abundance of isotopes.
    • Define “natural abundance” of an isotope.
    • Predict/Estimate the average atomic mass of an element from the relative abundance of each of it’s naturally-occurring isotopes.
    • Convert percentages to fractions and decimals.
    • Calculate average atomic mass of an element when provided with the exact atomic masses of isotopes and their natural abundances.
