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