Do metals have any specific characteristics?

Although there are many more, these are the four main properties of metals.

Because of the way that light reacts with their surfaces, metals frequently have luster—that is, they seem to "shine"

Because of their natural tendency to be malleable, metals can deform under compressive stress and become thin sheets.

In contrast to their malleability, metals also have a tendency to show ductility, or the capacity to flex under tensile stress and form into a thin wire.

Excellent electrical and thermal conductivity is another important property of metals. The solid state of these materials facilitates easy electric current flow and faster heat energy transfer.

Metals generally exhibit characteristics such as conductivity, malleability, ductility, luster, and high melting and boiling points. They also tend to form positive ions.
