Chemistry unit 2
| Question | Answer |
|---|---|
| Lewis diagram | Short hand version to show the valence electrons for main group elements |
| Process of light being absorbed | Energy js added from an outside source- electron js moved from ground state gk excited state |
| Excited state | Highest energy |
| Ground state | Lowest energy |
| Bohr | 4th model- said that electrons only have a 8 energy levels and that they lived on only thoose four levels |
| Schrödinger/Heinsbury | Discovered that their are diffrent sub levels that electrons can exist un and each sub level had a specific amount kf energy required to reside there |
| Process of energy being released | Too unstable to remain in excited state sk the electron falls back to the ground state and releases energy in thr state of a photon |
| Photon | Packet kf light energy- soecifc gk each transition kf electrons |
| Larger fall from electrons | More energy realesed (violet color) |
| Smaller fall | Less energy realesed (red color) |
| Pauli exclusion | If electrons occupy the same orbital they must have opposite spins |
| Aufbau principle | Electrons will till the lowest orbital before moving to the next |
| Hunds rule | Electrons will distribute amount sublevel before occupying with diffrent spins |
| Cations | Loosing electrons (+) |
| Anions | Gaining electrons (-) |
