The scientist(s) that is repsonsible for the Bohr Model is

• JJ Thompson

• John Dalton

• Ernest Rutherford

• Schordinger & Heisenberg

• Niels Bohr

The results of the Gold Foil Experiment led Rutherford to discover

• that the nucleus is positively charged

• that the atom is a solid sphere

• that the atom is mostly empty space

• that electrons exist

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

The results of the Cathode Ray Tube experiment led Thompson to believe

• The atom is a positively charged particle with negative electrons distributed through out

• The atom is an electron cloud

• The atom is mostly empty space

• The atom is a solid sphere

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 Electron Cloud Model of an atom

• tells us the exact location of an electron and its speed at the same time.

• is fluffy and all white

• states that electrons can only behave as a wave or a particle but never both.

• is a mathematical representation of the possible location of electrons around the nucleus.
