| Question | Answer |
|---|---|
| JJ Thompson | Plum Pudding Model - discovered electrons using tubes - electrons spread evenly |
| Rutherford | Gold foil experiment - atom is mostly empty space - small, hard, dense, positive nucleus |
| Bohr | Planetary Model - electrons in an orbital |
| Schrodinger | electrons are waves and particles of matter - electron cloud - orbital is the probable location for electrons |
| Heisenberg uncertainty principle | can know where the electron is or its momentum |
| ion | charged particle formed when an atom gains or loses electrons |
| isotope | atoms with the same number of protons but diff number of neutrons |
| average atomic mass | (% abundance)(mass) + (% abundance)(mass) ... |
| Wave - mechanical model | current model - orbitals of electron clouds where you can find the electrons - 2 electrons fir in each orbital - four orbital shaped (s,p,d,f) |
| ground state | most stable/lowest energyn |
| 7 diatomic elements | Hydrogen, Oxygen, Fluorine, Bromine, Iodine, Nitrogen, Chlorine (HOFBrINCl) |
