  1. Jackson Aull Atoms, Elements, and Compounds

  2. Chapter 1: Particle Theory and Classification of Matter

  3. Directions: Drag and drop the labels onto the proper state of matter. Use the arrow tool to show a state change and indicate whether energy is gained or lost.

  4. Directions: Fill in the hierarchy below with the classifications of matter. Briefly define each. Matter Pure Substance Mixtures Compounds A compound is when 2 or more chemical substances combine. Elements Elements are a chemical substance formed from an atom Homogeneous mixtures Homogeneous mixtures are mixtures of the same chemical substance or element. Heterogeneous mixtures Heterogeneous mixtures are mixtures that contain different chemical substances or elements.

  5. Chapter 2: Atomic Theory and Model

  6. Directions: Drag and drop the contribution to the Atomic Model into the space beneath the appropriate scientist. In the text boxes below, label the scientist and briefly describe their contribution to the Atomic Theory, including any experiments they ran. Democritus came up with everything is made of atoms and they were physically but not geometrically invisible. Atoms are always in motion and indestructible and there are an infinite amount. John Dalton said that all matter was made of atoms and was indestructible and invisible. Elements had atoms differing in size and mass. J.J. Thomson discovered electrons in atoms. He thought of them as being positive and negative charges. Ernest Rutherford believed that the atom has a tiny and heavy nucleus. He found this out by doing an experiment with gold foil. Niels Bohr’s theory of atoms were that the protons stayed in the middle and electrons orbit around them in a ring made up of certain electrons.

  7. Find images online that demonstrate how small atoms are (e.g. Earth:soda can = soda can:atom). Upload them below by choosing “Insert” from the menu and choosing the “Image” option. Include a reference below. Include your reference link here.

  8. Chapter 3: Atomic Structure and Notation

  9. Directions: Drag and drop the characteristics below into the columns for the subatomic particles they describe.

  10. Directions: Drag and drop the subatomic particles onto the rings below to build an atom of oxygen. Use the copy and paste function to create as many of each type of subatomic particle as you need. Write the atomic notation for oxygen in the box at right. 8 O 16

  11. Directions: Fill in the boxes with the correct numbers for protons, neutrons, electrons, atomic number, and mass number for the following elements. 29 86 74 35 136 110 29 86 74 79 26 54 158 52 108

  12. Chapter 4: The Periodic Table

  13. Directions: Find a periodic table online and fill in the table below. Potassium Transition metals 2 77 192.22 Non-reactive Conductive Noble Gases 8 36 83.798 High None Post-transition Metals 4 82 207.2 Reactive Little

  14. Directions: Draw and upload a symbol that represents the meaning of each word below. Upload them below by choosing “Insert” from the menu and choosing the “Image” option. 6 C Carbon 12.011 B Al B C N O F Ga In

  15. Chapter 5: Chemical Symbols, Formulas, and Compounds

  16. Directions: Fill in the table below with the correct compound formula or name.

  17. Directions: Using the table of combining capacities (CC) and the criss-cross rule, fill out the table below.

  18. Directions: In the box below, list three things you have learned and two things you wonder about chemical symbols, formulas, and compounds, and draw one symbol that represents these concepts to you. Type your answer here:

  19. Drag and drop the definition into the space next to the correct term.

  20. Extension Activity Create an extensive and detailed account of what you learned in this unit. You should include … • The big picture - what are the one or two points that really summarize this unit for you? • What were the new things you discovered? • What surprised you? • What was most interesting? • What questions do you now have after completing it? • A summary of each lesson’s key concepts, including pictures and information Submission • You will fulfill the requirements above by adding, and filling out, subsequent slides • Numbers 1-5 above can be done on one or two slides • Number 6 will utilize at least a single slide for each lesson to properly summarize the content
