SCIENCE REVIEW

The person who thought that electrons orbited the nucleus, like planets orbiting the sun?

• Dalton

• Rutherford

• J.J Thomson 

• Bohr

The atom is mostly an empty space and  its mass is concentrated in the nucleus, where you find the protons and neutrons.

• Dalton  

• Rutherford

• J.J Thomson 

• Bohr

This is 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.

• Use a large amount of candy in the center with random candies in circles around the center

• Place candy randomly at will.

• Put candies in a giant circle

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

• 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.

• The nucleus would only hold protons and no neutrons.

•    Absolutely nothing.

Compare or Contrast  Bohr's and Rutherford's atomic models

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

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

• Bohr improved Rutherford's model by proposing energy levels of electrons.

• Rutherford improved Bohr's model by proposing energy levels of electrons

Describe the Quantum-Mechanical Model of the atom

• Describes an electron probability distribution that determines the most likely location of an electron.

•   is the currently unaccepted atomic model.

• makes predictions based on Bohr’s wave equation.

• Everything is not right about this model

The Heisenberg Uncertainty Principle

• States that the position and momentum of an electron in an atom cannot be found precisely because measuring the electron changes its momentum.

• States that the position of an electron can be found by measuring its momentum.

• Assumes that the electrons takepositions predicted by Bohr's theory.

• That the mathematical equation is impossible to equate
