Aluminum is a
Correct answer: A. Metal
- A. Metal
- B. Non Metal
- C. Photo conductor
- D. Semiconductor
Explanation
Aluminum is a metal because it possesses all the characteristic properties of a metal. It is lustrous, malleable, ductile, and a good conductor of heat and electricity. Metals have a free electron structure which allows them to conduct electricity.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
