Which of the following best describes a metal? brittle, shiny, and solid brittle, dull, and low density malleable, shiny, and able to conduct heat or electricity malleable, dull, and solid, liquid, or gas at room temperature?

Answer : The correct option is, Malleable, shiny, and able to conduct heat or electricity.

Explanation:

Metals : Metals are the elements which can easily loose electrons and forms cations.

Properties of metals :

They are lustrous (shine).They are malleable and ductile (flexible).They conduct heat and electricity.The metallic oxides are basic in nature.They form cations in an aqueous solution.

Non-metals : Non-metals are the elements which can easily gain electrons and form an anion.

Properties of non-metals :

They are non-lustrous.They are brittle and hard in nature.They do not conduct heat and electricity.The non-metallic oxides are acidic in nature.They form anions in an aqueous solution.

Hence, from the given options the correct option for metal is, Malleable, shiny, and able to conduct heat or electricity.
