Hey chanmille! Sure I can answer it :-)
Metals have numerous properties.
The first one is luster, which indicates the shine of a certain metal.
Next, malleability, it's the ability of a metal to be hammered into thin sheets.
Ductility is the ability of the metal to be drawn into wires.
Thermal conductivity and electrical conductivity is the ability to conduct heat and electricity, respectively.
Metals have these properties because of the sea of valence electrons that reflects light and makes it bendable...
I hope I have helped you
