Question

According to the band theory, which of the followingprovide(s) an explanation for the high electrical conductivity ofmetals? 1. a partly filled conduction band 2. a valence band overlapping an empty conduction band 3. a filled valence band 4. a large gap between the valence band and the conductionband is it ? a. 1 &2 b. 1 & 3 c. 3 d. 3 & 4 e. 4 According to the band theory, which of the followingprovide(s) an explanation for the high electrical conductivity ofmetals? 1. a partly filled conduction band 2. a valence band overlapping an empty conduction band 3. a filled valence band 4. a large gap between the valence band and the conductionband is it ? a. 1 &2 b. 1 & 3 c. 3 d. 3 & 4 e. 4

Explanation / Answer

The answer for this problem is A 1 &2 the reason is that a valence band that is overlapping an emptyor partical filled conduction band in the definition ofconductivity of the band theory. the conduction band can be emptyor partially filled for conductance. 3. is actually the reason noble gass are inert. and 4 is the definition of a insulator.
