Answer
Brief Explanations:
Metals are good conductors of heat and electricity, have a luster, and are malleable and ductile. Examples include iron, copper, aluminum. Non - metals are poor conductors of heat and electricity, are often brittle, and lack luster. Examples are oxygen, nitrogen, carbon. Metalloids have properties intermediate between metals and non - metals, such as being semiconductors. Examples are silicon, germanium, boron.
