5 True/False Questions

1. bohr → created the plum pudding model; plums are negative particles pudding is positive; discovered the electron

   True        False

2. aufbau principle → an orbital can only hold two electrons and they must have opposite spin

   True        False

3. increase → electronegativity periodic trend

   True        False

4. increase → atomic radius group trend

   True        False

5. shielding → used quantum theory to write and solve mathematical equation describing the location and energy of an election in an hydrogen atom

   True        False
