Brittle
Im not sure about the atomic mass bit but Lanthanum is a silvery white, malleable, ductile, and soft rare-earth metal xx
It depends on how thick the gold wire is. Gold is extremely ductile.
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!

In colloquial terms, it is "strong". It can take a high load, and return back to an undamaged, undeformed state afterward. If the yield strength is equal to or very close to the ultimate tensile strength, common when it is a very high value, that indicates the material is not very ductile. Glass is a material like this. You can load it very high, but it will break rather than "stretch".

Non metals are brittle. They are neither malleable nor ductile.

Nonmetals
Ductile metals are metals that5 can be shaped and pulled. Gold is a example of a ductile metal so in other words, yes it is a type of metals. Ductility is a property of some metals. It is also a property of materials other than metal.
Nonmetals have properties opposite those of themetals. The nonmetals are brittle, not malleable or ductile, poor conductors of both heat and electricity, and tend to gain electrons in chemical reactions. Some nonmetals are liquids. These elements are shown in the following figure.
Yes, it is. All the metals are malleable and ductile
Malleable property describes the property of a substance such that it can be made into sheets by striking. Ductile property describes the property of a substance that it can be drawn into wires. For example: Aluminium, it is available in sheets and even in the form of wires.
no they're not malleable and ductile
