A key reason this fact has not been accepted is the lack of a cogent argument, based on fundamental physical ideas, justifying it. In the paper, this question is re-examined, based on a generalization of conventional energy band theory that applies to finite, periodic solids, in which d's...
The energy band structure shows the valence and conduction bands of the material. The valence band represents the outer-most shell of the electrons of an atom. Moreover, the conduction band represents the energy level where the electrons can freely...
How does the band theory of solids lead to the classification of solids into conductors, semiconductors and insulators? Give typical values of band gaps for semiconductors and insulators. Explain why scientists use semiconducting materials for solar cells Which...
Most people would be able to offer a technically correct answer, and almost none of them would be interesting. Or maybe the host is wondering who it was that played drums that night, as part of the bar's live music. Who played the drums for some specific band/album/track/concert/tour/...

Using a band diagram, explain how magnesium can exhibit metallic behavior when its 3s band is completely full. Please explain the activity series of metals. How can I determine if one element displaces another? What happens when sulfur reacts with iron? Doe...
(Hint: Think about what air is made of atoms and molecules. Think about where energy can go in the air that is different from the kine Explain the difference between intensity and solar constant. How does the band theory of solids lead to...
Electronic Transition Selection Rule: The selection rules are the sets of changes occurring in the quantum numbers due to the transition of one or more electrons from one state to another. The transition probability of electrons can never be zero. ...
Surface tension is the phenomenon by which the surface of liquids behaves like a stretched elastic membrane. From the molecular point of view, it is feasible to understand that the molecules of the liquid that are at the liquid-gas boundary (surface of the liquid...
What are the differences between band broadening and peak in chromatography? Explain the general principle of chromatography. Be sure to mention retention time, mobile phase, and stationary phase. Chromatography is a key technique used to separate ...
