A student is asked to build a model of an atom with 6 protons and 6 electrons. The student is then asked to make an identical model of the same atom but make it an ion. To be successful in this project, the student will: A. Put six protons in the center of the model, and six electrons around the outside, then add one electron or take away one electron to make an ion.

b. Place electrons and protons in the center of the atom and create an ion by adding one more proton and one more electron to the center of the atom.

c. Put the electrons in the middle of the model and distribute the electrons around the protons. The ion will have seven protons.

d. Put six protons in the center of the atom and distribute the electrons around the protons. The ion will look the same but have seven or five electrons.
