Module 2 Exam Review
This review is neither a replica of the exam nor does it contain every concept in the module. It is always best practice to review all lessons and assessments. Resubmitting is a great way to review/learn and improve your grade. There are approximately 32 questions (about 3 are essays) on the regular exam; approximately 42 questions (about 5 are essays) on the honors exam. The number in parenthesis is the lesson. None of the honors lessons are in this review. The answer key is after the review. You will need a calculator and the periodic table of elements.
1. Explain how theories become accepted. Are they ever replaced? (1.03; 2.01)
2. Explain the importance of the scientific method. (1.03; 2.01)
3. What is the importance of using models in science? (1.03; 2.01)
4. List the 5 postulates of Dalton’s Atomic Theory. (2.01)
5. Describe Crookes Experiment. (2.01)
6. Describe how Thomson’s work expanded upon Crookes. (2.01)
7. Explain Rutherford’s Gold Foil experiment and relate it to Thomson’s work. (2.01)
8. Describe Chadwick’s work in Chemistry. (2.01)
9. Describe the current model of the atom. (2.01)
10. What do we know about an atom if we know the atomic number? (2.02)
11. What does the atomic mass tell us about an atom? (2.02)
12. How many protons, neutrons and electrons are in an atom of Carbon? Explain how you determined them. (2.02)
13. How can an atom be electrically neutral? (2.02)
14. The atomic number of silver (Ag) is 47. A silver isotope has a mass of 108. How many electrons, neutrons and protons are in an atom of silver? Explain how you determined these. (2.02)
15. Define isotopes. Compare and contrast two isotopes of the same element.(2.03)
16. Two naturally occurring isotopes of calcium are calcium-42, calcium-44. How many protons are in a single atom of calcium-42? (2.03)
17. Two naturally occurring isotopes
