Answer
Brief Explanations:
Metals are good conductors of heat and electricity, malleable, and ductile. Examples include iron, copper, and aluminum. Non - metals are poor conductors of heat and electricity, often brittle, and may be gases at room temperature. Examples are oxygen, nitrogen, and sulfur. Metalloids have properties intermediate between metals and non - metals, they are semi - conductors, and have some metallic and non - metallic characteristics. Examples are silicon, germanium, and boron.
