Question

what kind of force will operate when 2 atoms come closer to each other?​

Answer 1

Answer:

Electric potential energy between charges

We know from Coulomb's law that two charged objects attract or repel each other with a force proportional to 1/r2, i.e. inversely proportional to the distance squared. So when the charges get closer together, the force of attraction or repulsion gets stronger.

Answer 2

Answer:

Electric potential energy between charges

We know from Coulomb's law that two charged objects attract or repel each other with a force proportional to 1/r2, i.e. inversely proportional to the distance squared. So when the charges get closer together, the force of attraction or repulsion gets stronger.
