Question

identify three characteristics of metals. metals can be stretched into a long string. metals can be easily shaped. metals are highly reactive with noble gases. metals are hard but can break down into dust. metals usually have high conductivity of electricity and heat. metals can exist in solids and gas states, but not liquid.

Explanation:

Metals are ductile (can be stretched into wires), malleable (can be easily shaped), and good conductors of heat and electricity. They are not highly reactive with noble - gases, not easily broken into dust, and can exist in solid, liquid (e.g., mercury), and under extreme conditions, gaseous states.

Answer:

Metals can be stretched into a long string.
Metals can be easily shaped.
Metals usually have high conductivity of electricity and heat.
