Answer;
Metals-
-Shiny surface
-Good conductor of electricity
-Good conductor of heat
-Malleable
Non- Metals
-Dull surface
-Poor conductor of heat
-Poor conductor of electricity
-Brittle
Explanation;
-Periodic table shows three different groups of elements. The metalloid group separates the metals from the nonmetals. Elements to the left are metals and nonmetals are to the right. The exception is the element hydrogen. Hydrogen has properties of a nonmetal at normal temperatures and pressures.
-Metals are good conductors of heat and electricity, and are malleable (they can be hammered into sheets) and ductile (they can be drawn into wire). Most of the metals are solids at room temperature, with a characteristic silvery shine (except for mercury, which is a liquid). Nonmetals are usually poor conductors of heat and electricity, and are not malleable or ductile; many of the elemental nonmetals are gases at room temperature, while others are liquids and others are solids.
