Kinetic energy is in anything that is moving. When two atoms are forming bonds they are either sharing electrons or trading electrons. That being said I would imagine that kinetic increases. Only it depends on the context of the problem. Potential energy is the ability to do work which has a lot to do with mass and weight. And although atoms are small, any increase in mass, and hence increase in weight, increases an objects potential energy as well..
