Answer 2

$\huge\frak{\underline{\underline{\red{Answer}}}}$

➡ 1.a substance which has a molecular structure built up chiefly or completely from a large number of similar units bonded together, e.g. many synthetic organic materials used as plastics and resins.

➡ 2.Metals are malleable:This means that metals can be beaten into thin sheets with hammer. If we take a piece of aluminium metal and beat it with a hammer,we will find that the piece of aluminium metal turns into a thin aluminium sheet,without breaking. Thus we can say that aluminium metal is malleable.
