Rutherford and Bohr

Who thought that electrons orbited the nucleus, like planets orbiting the sun?

• Dalton
• Thomson
• Rutherford
• Bohr

His atomic model included a dense positive core in an atom, surrounded by negatively charged particles:

• Joseph Thomson
• Niels Bohr
• Ernest Rutherford
• John Dalton

Rutherford's gold foil experiment provided evidence that...

• Negative and positive charges are spread evenly throughout the atom.
• Alpha particles have a positive charge.
• Gold is not a dense as previously thought.
• There is a dense positively charged nucleus at the center of an atom.

What way could you design a real life example of the Bohr model?

• Use a large amount of candy in the center with random candies in 3D standing wave like formations.
• Place candy randomly at will.
• Put candies in a giant circle
• Use a large amount of candy in the center with random candies in circles around the center.

What would result if the Modern Model of the atom was never discovered after the previously made atomic theory?

• The nucleus would only hold protons and no neutrons.
• Electrons would be believed to be orbiting the nucleus in circular paths rather than 3D standing waves.
• Electrons and Protons would be held together within the atom.
• Absolutely nothing.

How would compare or contrast Bohr's and Rutherford's atomic models?

• Bohr improved Rutherford's model by proposing energy levels of electrons.
• Bohr improved Rutherford's model by proposing protons and electrons are together in the atom.
• Rutherford improved Bohr's model by proposing energy levels of electrons.
• Rutherford improved Bohr's model by proposing protons and electrons are together in the atom.
