15 Questions
Which physicist guided the Geiger-Marsden experiment, also known as the Rutherford gold foil experiment?
Ernest Rutherford
What was the purpose of the Geiger-Marsden experiment?
To test the plum pudding model
According to the plum pudding model, how were electrons arranged within an atom?
Floating within positively charged matter
What particles were fired through the gold foil in the Geiger-Marsden experiment?
Alpha particles
What did Democritus name the fundamental particle that cannot be further divided?
Atomos
According to J.J. Thomson's cathode ray experiment, what did he conclude about the atom?
The atom can be subdivided into smaller particles and contains a negatively charged electron
What did Ernest Rutherford discover in his gold foil experiment?
Atoms are mostly empty space with a central positively charged nucleus
What was the atomic model proposed by J.J. Thomson called?
Plum pudding model
What did the Ernest Rutherford gold foil experiment falsify?
The idea that atoms are composed of small negatively charged electrons surrounded by positively charged matter
Why did Rutherford choose to fire alpha particles through gold foil in his experiment?
Gold is a heavy element that is exceptionally malleable and can be formed into thin foil
Which of the following statements is true about Ernest Rutherford's gold foil experiment?
Some of the alpha particles were deflected and some even bounced back towards their source.
What did the Rutherford gold foil experiment demonstrate about the atom's structure?
The atom is composed of mostly empty space.
Why did some of the alpha particles bounce back towards their source in the gold foil experiment?
The alpha particles were positively charged and repelled by the positively charged nucleus.
What did the gold foil experiment demonstrate about the composition of the atom?
The atom is composed of mostly empty space.
