Solution

Aluminum is silvery-white colored metal.
It is a malleable, ductile, light-weighted, and strong material.
It is also corrosion-resistant and a good conductor of heat and electricity.
The reflective coating for telescope mirrors is often made of aluminum, and the protective coating that sits on top of the reflective coating is typically made of silicon dioxide.
