Chemistry
| Question | Answer |
|---|---|
| Electricity | used in the late 1870's to aid in the study of atoms and their properties |
| Postitive Electrode | Cathode |
| Negative Electrode | Anode |
| Rutherford | discovered that when you placed a radioactive elemnt in a lead box with a small hole in it, a high energy particle was emmited |
| Laser ( 3 Particles ) | Alpha, Beta, Gamma |
| Rutherford shot at what type of foil | Gold (Au) |
| The scatter patterns were deflected differently if they hit the | Nucleus |
| Wavelength | y (upsidedown) |
| Frequency | v (Curved) |
| ROY. G. BIV | Red orange yellow green blue indigo violet |
| As frequency gets bigger | y (wavelenth gets smaller) |
| C= Speed of Light | 3.00*10^8 m/s |
| Energy= Planks constant * frequency | E= HvH= 6.626*10^-34 [J*s] |
| Line Spectrum | charateristic Property used to identify an element |
| Lowest electron state | Ground State |
| Anything above GS | is an Excited State |
| Becomes an excited state when | energy is absorbed |
| Lose an electron | Cation |
| gain and Electron | anion |
| Plum Pudding Model | ATOM CONSISTED OF A UNIFORM POSITIVE SPHERE OF MATTER IN WHICH THE ELECTRONS WERE EMBEDDED |
