chapter 24 - particle physics Flashcards
1
Q
plum pudding model
A
atom contained neg electrons embedded in a sea of uniform pos charge
2
Q
Rutherfords alpha scattering experiment
A
- fired a narrow beam of alpha particles with the same KE at at piece of thin gold foil
- alpha was scattered by foil and detected on a screen - when they hit the screen produced a speck of light
3
Q
Rutherfords alpha scattering experiment observations/ conclusion
A
- most passed through with little scattering - mostly empty space
- very few were deflected - mass was mostly concentrated in a small area - of positive charge
