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 |
