(a)
Interpretation:
The MO diagram of semiconductor should be drawn.
Concept introduction:
According to band theory, solids are classified as conductors, semiconductors, and insulators.
As per band theory, Bands are continuum of energy levels. The bands are of two types: valence band and conduction band.
Valence band is the band that holds valence electrons and conduction band is the band which is slightly higher in energy than valence band. On the basis of band theory, a partly filled band shows conduction and fully filled band doesn’t show conduction.
(b)
Interpretation:
The MO diagram of insulator should be drawn. The reason for the higher electrical conductivity of semiconductors should be explained.

- Suppose the rate of evaporation in a hot, dry region is 1.76 meters per year, and the seawater there has a salinity of 35 ‰. Assuming a 93% yield, how much salt (NaCl) can be harvested each year from 1 km2 of solar evaporation ponds that use this seawater as a source?arrow_forwardhelparrow_forwardExplain why only the lone pairs on the central atom are taken into consideration when predicting molecular shapearrow_forward
- (ME EX1) Prblm #9/10 Can you explain in detail (step by step) I'm so confused with these problems. For turmber 13 can u turn them into lewis dot structures so I can better understand because, and then as well explain the resonance structure part. Thanks for the help.arrow_forwardProblems 19 and 20: (ME EX1) Can you please explain the following in detail? I'm having trouble understanding them. Both problems are difficult for me to explain in detail, so please include the drawings and answers.arrow_forward(ME EX1) Prblm #4-11 Can you please help me and explain these I'm very confused in detail please. Prblm number 9 I don't understand at all (its soo confusing to me and redraw it so I can better depict it).arrow_forward
