Question
Part A
What makes a conductor different from a semiconductor different from an insulator? Choose one
A) conductor has more electrons to conduct electricity, whereas a semiconductor does not have so many electrons and an insulator has few or none.
B) In conductors, the molecular orbitals are delocalized out over the entire molecule, forming bands. In semiconductors the delocalization is somewhat less, and in insulators there is no delocalization of orbitals.
C) The number of and bonds on an atom determines the number of neighbors the atom can have.
D) The electrons in the conductor must make only a tiny transition to be in the conduction band, whereas the other two types of material have increasing transition energies. Part B
Explanation / Answer
correct answer :
D) The electrons in the conductor must make only a tiny transition to be in the conduction band, whereas the other two types of material have increasing transition energies
Explanation :
in conductors there is very less energy is required to tansition.but in semiconductors and insulators require more energy for transition.
