What are elements that can be hammered into shapes?
Elements that can be hammered into shapes are typically metals, particularly those that are malleable and ductile. Examples include gold, silver, copper, aluminum, and iron. These metals can be easily deformed without breaking, allowing them to be shaped into various forms through processes like forging or stamping. Non-metal elements, such as certain allotropes of carbon (like graphite), can also be manipulated but are generally less common in traditional shaping applications.
What property of nonmetals is the opposite of malleable and ductile?
Brittle
How long is one ounce of gold made into wire into kilometres?
It depends on how thick the gold wire is. Gold is extremely ductile.
What is lanthanum atomic mass?
Im not sure about the atomic mass bit but Lanthanum is a silvery white, malleable, ductile, and soft rare-earth metal xx
How many feet in a troy ounce of silver wire?
It depends on how thin the wire is. Silver is very ductile. According to one source(*), an ounce of silver can be drawn out into a wire 60 miles long (316,800 feet) - such a wire would make a human hair look very thick by comparison. As a point of comparison, the same source notes that an ounce of gold, the most ductile of metals, can be drawn out into a wire 1300 miles (6,864,000 feet) long!
