Detailed explanation-1: -The correct answer is Conductors. Do not conduct electricity. Metals are lustrous and have a shiny appearance. Non-metals have a dull appearance.
Detailed explanation-2: -Since metals generally have high melting points, the low melting point is not a characteristic of metals.
Detailed explanation-3: -In general, metal properties are as follows: Metals reflect light-they are shiny, not dull. Metals conduct both heat and electricity well. Metals have a high melting and boiling point and are solids at room temperature (except mercury).
Detailed explanation-4: -Properties of Nonmetals In general, non-metals are brittle, dull, and poor conductors of heat and electricity.
