A cathode ray tube shows a glowing beam bending toward the positively charged plate. Which conclusion is best supported?
In Rutherford's gold foil experiment, most alpha particles pass through the foil while a few deflect sharply. What does this observation show?
In Millikan's apparatus, a charged oil drop hangs motionless between two metal plates. Which forces on the drop are balanced?
A cathode ray tube gives the same beam behavior when different metals are used for the electrodes. What claim does that support?
In a gold foil setup, only about 1 in many thousands of alpha particles bounces back toward the source. Which idea does this rule out?
J. J. Thomson measured how much a cathode ray beam bent in electric and magnetic fields. What did these measurements let him calculate?
Which result came from J. J. Thomson's cathode ray experiments?
Which result is correctly matched with Ernest Rutherford's gold foil experiment?
Millikan measured the charge of an electron. Combined with Thomson's charge-to-mass ratio, what did this let scientists calculate?
Which scientist used cathode ray tubes and then proposed the plum pudding model of the atom?
Which scientist's experiment corrected the plum pudding model by showing that positive charge is concentrated in the center?
Which experiment gave the strongest evidence that atoms contain negatively charged particles?
Which experiment supports the claim that an atom is mostly empty space?
Which experiment supports the claim that electric charge comes in small, identical units for electrons?
If the plum pudding model were correct, what would Rutherford's team have expected in the gold foil experiment?
