BIOBEYOND UNIT 6 CHEMICAL BASIS OF LIFE UPDATED ACTUAL
QUESTIONS AND CORRECT ANSWERS VERIFIED 2027 EDITION
1. During your explorations, what molecules did you find that make up the structural components of
a cell?
Carbohydrates Lipids Nucleic Acids Proteins
2. Identify in the graphic below which pieces you think are atoms and which you think are bonds.
Bond
3. Identify in the graphic below which pieces you think are atoms and which you think are bonds.
Atom
4. In 30-140 characters, give your own definition of an atom.
Fill in the blank
5. Which of the following would be a good definition of the atom according to Democritus?
A piece of something that is as small as possible
6. What was JJ Thomson's biggest difference from Democritus' model?
Atoms could be broken down into smaller pieces
7. Which scenario below do you think is most likely for this experiment's results? Make a hypothesis.
any answer
8. Why did this surprise Rutherford?
Thomson's model of the atom had a diffuse positive charge, so the particles should not have been
deflected very far
9. How was Rutherford's model different from his mentor, Thomson's?
Rutherford's model had a small, dense, positive nucleus
10. What differences does Bohr's model have compared to Rutherford's? Select all that apply:
Distinct energy levels for electrons Distinct orbits for electrons
11. How is Schrödinger's model different from Bohr's?
Electrons don't have orbits but have volumes they may occupy
12. Where is most of the mass in an atom located?
Nucleus
13. What makes up most of the volume of an atom?
Empty space
14. Connect the name of the scientist to their contribution to the modern model of atomic structure.
