Question

Identify statements true of metals. Choose one or more :A.Metals can conduct electricity.B.Metals are malleable.C.Metals are radioactive.D.Copper is an example of a metal.

Answer 1

Answer:

A.Metals can conduct electricity

B.Metals are malleable.

D.Copper is an example of a metal.

Explanation:

Metals are characterized mainly by being good conductors of heat and electricity (being copper the most known example), by possessing high density and being solid at room temperature (except mercury).

Its properties include malleability, ductility (property of metals to be molded into wires when subjected to tensile stress), toughness and mechanical strength.

Answer 2

Answer:

A. Metals can conduct electricity

B. Metals are malleable

D. Copper is an example of a metal

Explanation:

The metals are elements that have strong bonds. All of them are solid at room temperature and require high temperatures that would melt them and turn them into liquid, apart from the mercury, which is the only metal that is liquid on room temperature. Main characteristics of the metals are that they are good conductors of electricity, are malleable, ductile, and lustrous. While some metals are radioactive, the majority of them are not, so we can not put this as a general characteristic of them all. Some of the elements that are metals are copper, iron, nickel, mercury, tin, aluminium, silver, gold, potassium...
