- Explain why the particle in a box has quantized energy levels. Given that the Bohr model of hydrogen also has quantized energy levels, what does this imply about the electrons in hydrogen?What is the maximum number of electrons in (in the 5-th orbit of atom) the fifth principle energy level?(Quantum mechanics )Describe experiment and key observation. The X-ray diffraction pattern of aluminum foil. (b) The electron diffraction pattern of aluminum foil. The similarity of these two patterns shows that electrons can behave like X -rays and display wavelike properties What important basic principle do these two experiments prove?
