Electron Cloud Model - Assignment
Date
due:_____________
1. What part of Bohr’s model of the atom is still part of the electron cloud
model?
2. What part of Bohr’s model has been changed?
3. What does an electron cloud represent?
4. Why do scientists have to use probabilities when trying to predict the
location and movement of electrons?
5. On p.117, the textbook explains orbitals with an analogy. If you were
actually to map your location as described, would it mean that you would
never have been in a particular location if there were no dots in that spot
or that you never will be in that location? Give two examples to help
explain your answer.
6. Explain your answer to the previous question in terms of electrons in
atoms.
