Atomic Model Project
Purpose: Students will be able to describe the structure of atoms, including the masses, electrical charges, and locations of protons and neutrons in the nucleus and electrons in the electron cloud.

Identify that protons determine an element’s identity and valence electrons determine its chemical properties, including reactivity.


Project Instructions:
Part 1: Atom Model

  1. Research one element from the periodic table between Lithium, atomic # 3 and Strontium, atomic # 38. (ASSIGNED IN CLASS)

  2. Make an accurate and neat 3-D atomic model representing the element you choose

Or make a clearly labeled 2-D model on a mini poster (minimum 11 in x 8in)

  1. Label each part of your atom and include the name of your element (on actual model or on an attached notecard)

    • The following must be present in your atom

      • Correct # of Protons

      • Correct # of Neutrons for one Isotope of your atom

      • Correct # and position of Electrons in energy levels (for a neutral atom)

  2. Your atom must be able to hang from the ceiling (it cannot be too large, too small or too heavy).

  3. You may only use non-perishable items to make your model (i.e. construction paper, styrofoam, toothpicks, paperclips, string, wire, paper, cotton balls, etc.).

      • Make sure the materials that you use accurately represent each atomic particle (i.e. Size, mass)



Part 2: Project Essay: Write an essay (or create a brochure) about your atom including all the following information. This must be written in complete sentences using correct spelling and punctuation.

    • Atomic # and Symbol

    • Mass number (average atomic mass rounded to the nearest whole #)

    • What determines the identity of your element?

    • Number and electric charge of the protons, neutrons and electrons

    • Whether your atom is metal, non-metal or metalloid

    • Number of valence electrons

    • Group # (is it a member of a certain family?)

    • Period #

    • Electron Configuration

    • Chemical properties

    • Physical properties

    • How did the element get its name? When was it discovered?

    • What are some common uses today (i.e., where might you find it?)

REFERENCES: list the resources for where you found the information - if online provide the complete URL, for books use standard format taught in ELA classes
