Question

which position on the graph represents two atoms that are not interacting? position 3 position 2 position 4 position 1

Explanation:

When two atoms are not interacting, they are far apart. On an energy - distance graph for two atoms, the position where they are far apart corresponds to a relatively high and constant energy level. As the distance between atoms decreases, they start to interact and the energy changes. Position 4 shows the atoms at a large distance where they are not interacting.

Answer:

Position 4
