Question

14) _________ are generally non malleable and non - ductile.

Answer 1

1) Malleability refers to a property of metals where the latter can be drawn into sheets easily. For example - aluminum foil

2) Ductility refers to a property of metals where the latter can be drawn into wires easily.

3) Non-metals are hard and brittle and hence when they are hammered to be drawn into sheets and wires they generally shatter or break down. Thus they are non-malleable and non-ductile

So, Non-metals are generally non-malleable and non-ductile.
