Question

why are metals good conductor of electricity whereas glass is a bad conductor of electricity give reason

Answer 1

Dear student, Electricity flows where there is flow of electrons metals are good conductor of both heat and electricity because there is free movement of electrons and the Electrons are not bonded with any particular atom but in case of a good conductor such as glass all the electrons are tightly bonded with the atoms so they are not free electrons hence it does not carry electricity.
