Question

(a) what kind of material are coal and lead? (b) do they show property of malleability and ductility?

Answer 1

nope!
coal do not show the property of malleability and ductility...
as it's a mineral made up of carbon... which is a non metal
but lead is a Metal and it's malleable too!!!
that's it

Answer 2

Hey mate !!

Coal is obtained from Carbon ( a non metal) and thus it does not shows d property of malleability or ductility..
Whereas Lead is a metal and thus it is both malleable and ductile..

Hope this helps☺☺
