Question

As two atoms approach one another in space, the potential energy decreases then increases as shown in the diagram below.

To what are these two changes attributed? [NOTE: p+ = proton, e– = electron]

A.

decreased potential: increased p+ e– attraction; increased potential: increased p+ p+ repulsion

✓ Correct
B.

decreased potential: increased p+ e– attraction; increased potential: increased e– e– repulsion

C.

decreased potential: decreased p+ p+ repulsion; increased potential: increased e– e– repulsion

D.

decreased potential: decreased p+ e– repulsion; increased potential: increased p+ p+ repulsion
