Question

iron is conducter of elecricity but when we pick up apiece of iron resting on the groundwhy dont elecric spark​

Answer 1

iron in its pure form conducts electricity very good due to easy ionization of electrons within it.

but when metals react with humidity in atmosphere then bases are formed which are poor conductor of electricity.

hence metals conduct electricity whereas atmosphere reacted metals or rust do not conduct electricity

Answer 2

Explanation:

A piece of iron resting on the ground has free electrons in it. The flow of electrons is missing in it. Hence, it doesn't have electric current.Therefore we don't get electrick shock when we touch it.
