In a complete sentence, describe the relationship between the independent and dependent variables in Model 1.
Model 2 - Number of Protons and Attractive Force
What is the independent variable in Model 2?

The attractive and repulsive forces in an atom are rather complex. An electron is attracted to the protons in the nucleus, but is also repelled by the other electrons in the atom. It is important to note, however, that the attractive force of the nucleus is NOT divided up among the electrons in the atom. Each electron gets approximately the full attractive force of the nucleus (minus the repulsive effects of other electrons). Compare the diagram below to set D in Model 2. Notice the similarity in attractive force.
What is the approximate attractive force on each electron below?
Which factor seems to have the greatest impact on the attractive force between two charged particles:
distance between particles OR difference in charge between particles?
Justify your answer with evidence from Model 1 and Model 2 above.
Would you expect to observe attraction or repulsion between the subatomic particles in Model 1?
What is the independent variable in Model 1?
What is the dependent variable in Model 1?
If the distance between a proton and electron is 0.50 nm, would you expect the force of attraction to be greater than or less than 0.26 x 10-8 N?
What is the dependent variable in Model 2?
In a complete sentence, describe the relationship between the independent and dependent variables in Model 2.
What would be the attractive force on a single electron if five protons were in the nucleus of an atom? Show mathematical work to support your answer.
Imagine that a second electron were placed to the left of a nucleus containing two protons (Model 2, Set D). Predict the force of attraction on both the original electron and the second electron.
