Answer:
Transition metals.
Explanation:
Conductor of electricity typically refers to any material or object that allow the conduction (transfer) of electric charge.
Tungsten (W), Copper (Cu), and Iron (Fe) all belong to the same family, whose members are generally used as conductors of electricity. This family is known as transition elements.
The transition elements refers to the chemical elements found in group III to XII (3-12) of the periodic table and typically has a d-orbitals (d subshell) that is partially filled with electrons.
Tungsten (W), Copper (Cu), and Iron (Fe) belongs to the family of transition metals.
Conductors of electricity are object or substance that conduct electricity. Currents can flow through them efficiently.
The Elements Tungsten (W), Copper (Cu), and Iron (Fe) all belong to the group/family called transition metals.
Transition metals forms one or more stable ions and they have incompletely filled d orbitals.
Generally, transition metals are good conductor of electricity. They are very good catalyst for chemical reaction.
