​

Answer 1

Answer:

Brittleness is not a characteristic of metals.

Explanation:

i. Ductility: Ductility is the physical property of a material associated with the ability to be hammered thin or stretched into wire without breaking. A ductile substance can be drawn into a wire. Examples: Most metals are good examples of ductile materials, including gold, silver, copper, erbium, terbium, and samarium.

ii. Brittleness: "Brittleness" (or 'lack of ductility') is simply the tendency of metals and alloys to form cracks during stress. Metals can yield elastically ("stretch") and then resume their original shape (up to a point) when the load is removed. Or they can yield "plastically" by flowing in response to the stress.

iii. Malleability: Malleability is a physical property of metals that defines their ability to be hammered, pressed, or rolled into thin sheets without breaking. In other words, it is the property of a metal to deform under compression and take on a new shape.

iv. Sonority: Sonority is the ability to produce a sound when struck. Metals are sonorous; they produce a specific sound when struck with a hard object.
