What characteristics define a metal?

Conducts heat but not electricity
Lustrous, malleable, ductile, and conducts heat and electricity
Made up of at least two different types of particles
Dull powdery solid that does not conduct heat or electricity

The correct answer is: Lustrous, malleable, ductile, and conducts heat and electricity

Metals are defined by their unique set of characteristics, including being lustrous (shiny), malleable (able to be hammered into shape), ductile (able to be drawn into wires), and having the ability to conduct both heat and electricity. Option A is incorrect because metals do conduct electricity. Option C is incorrect because metals are not defined by their composition or particle makeup. Option D is incorrect because metals are not dull or powdery and they do conduct heat and electricity.
