The Bohr model

Students often get confused between Rutherford’s model and Bohr model of an atom. They interpret the postulates of both these models to be the same, which is incorrect. Rutherford’s model differs from Bohr’s model in the following ways:

Question

100%

The image shows a potential energy curve for the interaction of two neutral atoms. The curve illustrates how the energy of the system changes as the distance \( r \) between the atoms varies. The two-atom system is in a vibrational state, indicated by the heavy solid horizontal line near the bottom of the curve.

**Graph Explanation:**

- The vertical axis represents the potential energy in electron volts (eV).
- The horizontal axis represents the distance \( r \) between the two atoms.
- The curve dives into a trough, reaching a minimum point, and then rises gradually, approaching zero as \( r \) increases.
- The minimum of the curve corresponds to the most stable configuration at \( r = r_1 \).
- The horizontal line indicates the vibrational state of the system, where the atoms are not at the minimum energy but in a quantized vibrational state.

**Questions:**

(a) At \( r = r_1 \), what are the approximate values of the kinetic energy \( K \), the potential energy \( U \), and the quantity \( K+U \)?

- \( K = \underline{\hspace{1cm}} \, \text{eV} \)
- \( U = \underline{\hspace{1cm}} \, \text{eV} \)
- \( K+U = \underline{\hspace{1cm}} \, \text{eV} \)

(b) What minimum (positive) amount of energy must be supplied to cause these two atoms to separate?

\(\underline{\hspace{1cm}} \, \text{eV}\)
