Explain the properties of metals and non-metals and how they differ.

Metals are generally lustrous, malleable, ductile, and good conductors of heat and electricity. They form basic oxides when they react with oxygen. Non-metals, on the other hand, are usually non-lustrous, brittle, and poor conductors of heat and electricity. They form acidic oxides when they react with oxygen and do not have the properties of malleability and ductility.
