Conceptual Chemistry Atomic theory + Periodic table Preview 2014 Send to Gene Easter GLEaster@sbcglobal.net by June 28, 2015 Please send your file named: your last name atomic 2015. Thank you Gene Name_________________ Grade______ Please use examples when possible. Thanks! Please answer all 16 questions 1. A. What is John Dalton” atomic theory? Chris’ PPT Use the CER Claim, Evidence Reasoning in paragraph form. 1. B What is Rutherford’s model of the atom? How is it better than Dalton’ model of the atom? Please do a Use the CER Claim, Evidence Reasoning in paragraph form. 2. What is the evidence supporting for the atomic theory? Review the activities we have done this week such as matter circus,( 8 were done in class, on the thrumb drive 19 more that can be done with simple material in your classroom) bimetallic rod, Dye in water, ice melting and freezing, evaporation, crystals, diamonds in the rough, electrostatics, Chris’s ppt’s, book, web etc.Use the CER Claim, Evidence Reasoning in paragraph form. 3. What holds atoms together in a solid element (cooper) or an alloy such as a stainless fork? Think balloon dancing we did in the hall--—It is not hydrogen bonding! 4. How is the atomic theory related to the law of conservation of mass in a closed system Use CER here. We did in class 2 examples. 5. What does an atomic number (Z) represent in a single atom of an element? 6. How are elements, compounds and molecules the same and different? Please use examples. P+, N0, and e- ‘ 7. How many s are there in a single neutral atom of 35Cl? The atomic number is 17 and the mass number is 35. 8. What are isotopes? Show the 3 isotopes of hydrogen. 9. What is the periodic law? What is the evidence for the periodic law? How is the law useful to chemists and teachers? Use CER here. 10.What are the properties and positions on the periodic chart of the following: A. metals B. metalloids C. nonmetals Please use examples of each type of element. Thanks! 11. What are the major trends of vertical columns and horizontals rows on the periodic chart? 12. Look at the elements in a vertical column (group) in the energy level models shown. What do you notice about the number of electrons in the outermost energy level (valence level)? What does this tell you about how the atoms in a group react? 13. Compare and contrast a scientific theory and a scientific law. Which is more powerful and which is more durable? Use CER. To help you answer the diference between theory and law. Look what how laws and theories do different things. See below Biology: cell theory, modern evolutionary synthesis, germ theory, particulate inheritance theory, dual inheritance theory Chemistry: collision theory, kinetic theory of gases, Lewis theory, molecular theory, molecular orbital theory, transition state theory, valence bond theory Physics: atomic theory, Big Bang theory, Dynamo theory, M-theory, perturbation theory, theory of relativity (successor to classical mechanics), quantum field theory Other: Climate change theory (from climatology), plate tectonics theory (from geology) Newton’s Law of universal gravitation.

There is a solid metal table with a cup of water sitting on it. Which of the following statements about the atoms and molecules of the table and the atoms and molecules of the water is TRUE? A. The atoms and molecules of both the liquid water and the table are moving. B. The atoms and molecules of both the liquid water and the table are not moving. C. The atoms and molecules of the liquid water are not moving, and the atoms and molecules of the table are moving. D. The atoms and molecules of the liquid water are moving, and the atoms and molecules of the table are not moving. 15. True or False? When a match burns, some matter is destroyed. a. True b. False 16. What is the reason for your answer to question 15? a. b. c. d. e. This chemical reaction destroys matter. The flame consumes matter. The mass of ash is less than the match it came from. The atoms are not destroyed, they are only rearranged. The match weighs less after burning.
