Concept explainers
Interpretation: The Rutherford atomic model needs to be sketched and its drawback needs to be explained.
Concept introduction: Rutherford’s atomic model describes that the nucleus of an atom is small and dense and possesses a positive charge and the electrons with negative charge revolve around the nucleus in a circular motion.

Answer to Problem 2A
Rutherford couldn’t explain why the electron doesn’t fall into the nucleus.
Explanation of Solution
Sketch of the Rutherford model is
The nucleus is densely packed with a positive charge and the electrons are revolving around it.
Rutherford’s atomic model, couldn’t explain
- The stability of electrons.
- It cannot explain the energy spectrum of an electron.
If electrons revolve in a circular motion thus, they radiate energy and if electrons lose their energy they fall into the nucleus and the atom becomes unstable but, this cannot be true as the atom is stable.

At the equivalence point for the titration, the moles of added HCl are equal to the moles of Na2CO3. One drop (or less!) past this is called the endpoint. The added HCl begins to titrate the thymol blue indicator itself. At the endpoint, the indicator color is ["", "", "", "", ""] . When you weren't paying attention and added too much HCl (~12 mL extra), the color is ["", "", "", "", ""] .
