Answer Posted / g venkateswarlu
copper is good heating and electricity.and its atomic number is 29 first orbit 2 electrons and second orbit 8 ele,3rd orbit 18 ele,still 4th orbit 1 ele is present ,it is freely move to other atom so copper is gud conductor.compare to aluminium,it is less weight ,less cost it is used in OH cables
