Thinking step
The periodic table is divided into three segments: metals and non-metals and transition metals. The metals are on the left hand side of the table. These are made up of the Group I and II elements. Group I elements are alkaline metals. Group II are alkaline earth metals. Both are good electron conductors. They have localized electrons to conduct current.
Transition metals are found in the middle. These are metals like iron and copper. They can change valencies or electrons. They are good electricity conductors.
Last, the right side is comprised of gases and solid. These are poor electron conductors.
