An avionics technician is classifying material samples based on atomic structure and electrical behavior. Match each material on the left with its correct electrical classification and atomic property on the right.
- SilverConductor with one loosely bound valence electron per atom, providing the highest electrical conductivity of any metal.
- GermaniumSemiconductor with four valence electrons forming a crystal lattice, exhibiting conductivity between that of a conductor and an insulator.
- MicaDielectric insulator with tightly bound valence electrons, offering high resistance to electric current and excellent breakdown strength.
- NichromeResistive alloy conductor engineered to oppose current flow and convert electrical energy into heat.
Answer
Silver matches the conductor with one loosely bound valence electron; Germanium matches the semiconductor with four valence electrons; Mica matches the dielectric insulator with tightly bound valence electrons; Nichrome matches the resistive alloy conductor.
Silver has one loosely held valence electron per atom, making it the most conductive metal; Germanium has four valence electrons, characterizing it as a solid-state semiconductor; Mica contains tightly bound electrons, establishing its function as a dielectric insulator; Nichrome is an alloy conductor formulated with high electrical resistivity for thermal dissipation.
