Description : Which of the following properties is generally found, in non-metals?' (1) Brittleness (2) Conductivity (3) Ductility (4) Malleability

Last Answer : (1) Brittleness Explanation: An important physical property of non metals is that they are brittle and hence cannot be beaten into sheets or drawn into wires. In other words, non-metals are non-malleable and non-ductile. Where stress is applied on nonmetals, they shatter into pieces.
