Answer:
(a). chemical properties.
• Metals react with dilute mineral acids to form metal salts while non-metals react with dilute mineral acids to form aqueous solutions.
• Metals easily react with air ( oxygen ) compared to non-metals.
(b). Physical properties.
• Metals are harder and ductile than non-metals.
• Metals conduct electricity while non-metals are insulators.
• Metals are solids at room temperature while non-metals are gases at room temperature.
