(D) The net force between the atoms is attractive at 75 pm.
▶️Answer/Explanation
Ans:B
Question
The potential energy as a function of internuclear distance for three diatomic molecules,\( X_2\), \(Y_2\), and \(Z_2\), is shown in the graph above. Based on the data in the graph, which of the following correctly identifies the diatomic molecules, \(X_2\),\( Y_{2}\), and \(Z_2\)?
