I. Solids exhibit an amazing range of electrical conductivities.II. Its magnitude ranges from 10-20 to 107 omh-1 m-1 .Which of the above statement(s) is/are correct?

Solids have a strong electrical conductivity that's why they are known as conductors. Their conductivity is dependent on their atoms' number of valence electrons. Such electrons are not tightly bound together and are free to pass.Solids exhibit a varying range of electrical conductivities, extending of magnitude ranging from 10–20 to 107 ohm–1 m–1.
