Atomic Structure and Periodic Table

ASSIGNMENT:

1. Produce a product (such as a timeline, brochure, or poster) that will show the development of the modern theory of the atom by identifying scientists and their experiments, conclusions, and contributions.

2. Include the historically important work of the following scientists:

• Dalton
• Thomson
• Rutherford
• Bohr

***You may search the internet to add to your timeline and sufficiently describe the major contributions to modern atomic theory by each of these scientists.

ASSIGNMENT:

1. Watch the video on atomic structure and create a bubble map on the Structure of the Atom.

2. You may include a drawing on your map.

1. Use the link above for practice with building atoms and looking at their structure.

2. Write 3-5 sentences about what you know about the structure of atoms.

ASSIGNMENT:

1. Watch the video and create a bubble map over the Characteristics of Isotopes. You may include a drawing if it helps.

2. Share your map with a neighbor and add anything you didn't have.

3. How are isotopes of the same element different? Write a summary statement answering this question using a complete sentence.

ASSIGNMENT:

1. Get a copy of the table above from me and fill in.

2. Write 3-5 sentences, including an observation about whether an atom of a particular element can gain or lose electrons? protons? or neutrons?

3. When you are done with this, see me! You are ready for your lab on calculating average atomic mass. Get a copy of the lab from me (see below)

ASSIGNMENT:

1. Watch the short video on Mendeleev's contribution to the periodic table.

2. Then do some research on his work and the work of Henry Moseley.

3. Write 3-5 sentences on their use of physical and chemical properties when assembling the periodic table as we know it.

ASSIGNMENT:

1. Visit the website above on the periodic table.

2. Write down at least 10 observations you can make about how the table is assembled using complete sentences. Please notice the tabs "properties", "orbitals", "isotopes" and "compounds" that you may change to see different information about the elements and their arrangements.

ASSIGNMENT:

1. Use the videos, textbook, worksheet and/or internet to help you color in the trends in the periodic table based on how it is arranged.

2. You will need to get a copy of the assignment "coloring the periodic table" from me as well as your own periodic table.

ASSIGNMENT:

1. Get a set of index cards.

2. On the front of each card, write the following terms: ionization energy, oxidation number, atomic radius, ionic radius, electron affinity and electronegativity.

3. On the back of the card, write the definition and a drawing of the term, using the video above, books and/or internet.

4. Be prepared to define or explain the terms when you bring me your cards (meaning---you may want to study them first!)

ASSIGNMENT: Watch the videos on electron configurations. Start with the one on the right.

1. As you watch, create a bubble map on Electron Configurations.

2. Then, choose 3 elements and write their electron configurations.

3. When you are ready, show me you know how to do this. I will select an element and you will complete the electron configuration for the element. Also, be prepared to identify the number of valence electrons the element has

ASSIGNMENT: Watch the video.

1) Draw an atom of your choice in its ground state.

2) Draw an atom of your choice in its excited state.

3) Describe how atoms can emit energy in the form of light. Be sure to include the formula.

ASSIGNMENT:

1) Complete the virtual lab above and describe the purpose of a flame test.

2) Come see me for a spectrometer.
