Note: "electricity" is not conducted, only electrical current (the flow of electrons) is. Electricity is the field that covers all things electrical. The wood in a pencil is an insulator. If it is wet, it is a poorer insulator, but only a poor conductor. The carbon (lead) in the pencil is a poor conductor. The metal holding the eraser is a good conductor. The rubber eraser is a poor conductor. You really have to address the conductivity of specific substances, not items that are build from a variety of substances.

Iron
A good conductor is a substance that will easily carry loose ions, also known as electricity. Many metals are good conductors. Conductors have many modern applications. Any wire that carries an electrical current has to be a conductor of some sort. On the contrary, substances that do not conduct electricity are known as insulators. Rubber is a very common insulator.
Al (s) apex
That would be water.
Oxygen. Carbon as diamond is a good electrical insulator, (graphite is an electrical conductor), silicon is a semiconductor so has limited electrical conductivity and aluminium is a metal and a good electrical conductor.
Copper is a good conductor, that's why it is used to make electrical wire.
Nitrogen is not a good electrical conductor.
