Metals: Found on the left side of the PT Properties: 1. malleable (can be hammered into sheets) 2. ductile (can be drawn into wires) 3. shiny (have luster) 4. good conductors of heat and electricity 5. high melting and boiling points
Nonmetals: Found on the right side of the PT Properties: 1. dull (lack luster) 2. brittle (can break easily) 3. poor conductors of heat and electricity 4. low melting and boiling points
Metalloids: Found on the “staircase” of the periodic table Properties: behave as both metals and nonmetals There are two exceptions: Al & Po are metals.
