1. When is the kinetic energy of an electron transformed into potential energy?

when it interacts with other electrons, decreasing its speed

when it interacts with other electrons without changing its speed


2. Atoms bond to form molecules. Which structures or regions of the atoms interact in these bonds?

electric fields of particles with no charge

electric fields of particles with negative charge

electric fields of particles with opposite charges


3. In particle accelerators such as the one shown, fields are employed to separate different subatomic particles. What type or types of fields are employed, and what characteristics do these particles need to have in order to be separated?

Both electric and magnetic fields are applied. Particles need to be charged.

Electric fields are applied. Particles need to come from the same type of atom.


4. If two electrons that are apart get pushed toward each other, how does the repulsion between them change?

Initial repulsion is high and increases as they approach.

Initial repulsion is low and decreases as they approach.

Initial repulsion is high and decreases as they approach.

Initial repulsion is low and increases as they approach.
