During the gold foil experiment, postively charged particles (alpha particles) were shot at an atoms thick piece of gold. What was observed?
The alpha particles were absorbed by the foil
All of the alpha particles bounced back
Most of the alpha particles went straight through but a few bounced back
All of the alpha particles stuck to the outside of the gold foil
During the Cathode Ray Tube experiment the beam bent towards the magnet's positive side. This meant that the beam was
Positively charged
Negatively charged
Neutrally charged
No Charge was observed.
The solid sphere model was developed
through a dream and a "greater power" speaking to Dalton
because Dalton copied Aristotle's ideas of the four elements (earth, wind, fire, & water) as his own
by Dalton experimenting with different substances and gasses and noticing patterns
because no one could come up with a better idea.
