  1. - + What did you observe between the proton and the electron?

  2. e- move towards the protons: they are attracted to each other

  3. What holds electrons in an atom?

  4. The attraction between the e- & p+

  5. - - What did you observe between the electrons?

  6. Do electrons like each other electrons?

  7. NO

  8. Conclusion….

  9. e- like p+ &…

  10. e- REPEL e- move as far away from each other…..

  11. However, they do exist in pairs (remember two per e- cloud shape)
