Atomic Structure – Part A 

Unit Objectives: By the end of this unit you should be able to

  1. Describe the structure of atoms, including the particles that make them up,
 

Try to hand things in every day.  Mrs. H WILL NOT grade more than 15 points on any day of this unit.

  1. Recognize that key scientists and experiments have contributed to the changes

      in the Atomic Theory,

  1. Tell the difference between atoms, ions, and isotopes,
  2. Describe the differences and similarities between different types of atoms,
  3. Explain how models of the structure of the atom have changed over time,
  4. Identify features and patterns on the periodic table, and
  5. Correctly use the periodic table to find general information.

    Our understanding of the structure of the atom has changed dramatically over the last 200 years.  Are we “finished” discovering?  (Does our current model accurately describe the structure of atoms?  Will we have a different model 200 years from today?  Why or why not?  
    15    		    
    Since Dmitri Mendeleev published the first periodic table of the elements, the table has grown as a new elements have been discovered.  Is the current periodic table complete?  Does it have all possible elements on it?  How do you know?  
    15    		    
    What, if anything, does the general public need to know about atoms?  Are scientists and students the only ones who should understand how to use the periodic table? Why?
