1.	(a). State any three differences between the physical properties of metals and non-metals. (b). Differentiate between metals and non-metals on the basis of their chemical properties. (c). State three reasons (of which at least one must be chemical) for believing that sodium is a metal. (d). State three reasons (of which at least one must be chemical) for believing that sulphur is a non-metal. (e). Which non-metal has been placed int he reactivity series of metals.
Answer» SOLUTION :a) The differences in Physical PROPERTIES of Metal & Non-metals b) The differences in Chemical Properties of Metal & Non-metals c) Sodium is a metal because it is solid, conducts electricity, forms basic oxides. d) SULPHUR is a non-metal because it is Brittle, non-ductile, Non-conductor of electricity, forms ACIDIC oxides e) Hydrogen
