Identify in the graphic below which pieces you think are atoms and which you think are bonds.
Bond
Identify in the graphic below which pieces you think are atoms and which you think are bonds.
Atom
In 30-140 characters, give your own definition of an atom.
Fill in the blank
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
What was JJ Thomson's biggest difference from Democritus' model?
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.
any answer
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
How was Rutherford's model different from his mentor, Thomson's?
Rutherford's model had a small, dense, positive nucleus
What differences does Bohr's model have compared to Rutherford's? Select all that apply:
Distinct energy levels for electrons
Distinct orbits for electrons
How is Schrödinger's model different from Bohr's?
Electrons don't have orbits but have volumes they may occupy
, Where is most of the mass in an atom located?
Nucleus
What makes up most of the volume of an atom?
Empty space
Connect the name of the scientist to their contribution to the modern model of atomic structure.
