Competency #6
Answer and Explanation
The correct answer is B.
Metals are malleable and ductile, not brittle. This means they can be hammered, stamped, rolled, and shaped without breaking. Gold is the most malleable metal, meaning it is ideal for creating a wide variety of shapes and forms, as are seen in jewelry. Aluminum is also very malleable and this allows an aluminum block to be rolled into the ultra-thin sheets we use every day- aluminum foil.
Metals can also be stretched into long, skinny wires. Typically, copper is used for wires due to its high ductility and electrical conductivity.
