1.

Which of the following statement is incorrect with respect to metallic or electronic conductivity

Answer»

Metallic conductivity depends on the structure of metal and its characteristics
Metallic conductivity depends on the NUMBER of electrons in the valencshell of atom of metal
The ELECTRICAL conductivity of metal increases with increase in temperature
There is no change in the structure of metal during electrical conduction

Solution :For metal,
As TEMP, increases RESISTANCE increases hence conductivity DECREASES.
