Numeric Response
Place the following in the numerical order of discovery (1 being the earliest- 5 being the most recent):
 

 24. 

          _____ Bohr- determined that electrons reside in energy levels that surround the nucleus

 

 25. 

          _____ Rutherford: Discovered the positive nucleus and that atoms were mostly empty space.

 

 26. 

_____ Quantum mechanical model- Electrons reside within orbits in energy levels whose location is based on probability


 

 27. 

_____ Thomson- discovered the electron. Placed electrons randomly in a positive surrounding (blueberry muffin model)

 

 28. 

         _____ Dalton- Atoms were solid speres with no smaller particles (like marbles)
