Sio2
Out of the substances listed, iron (Fe) would have the greatest ductility. Iron is a metal known for its high ductility property, meaning it can be drawn into thin wires without breaking. The other substances - carbon (C), silicon dioxide (SiO2), and sodium chloride (NaCl) - are not known for their high ductility.

Ductility is a physical property.
Ductility is a mechanical property of a material that describes its ability to deform under tensile stress without fracturing. It is not a physical state, but rather a characteristic of a material's behavior under certain conditions.
You can determine the ductility of a brazing paste by conducting a bend test on a brazed joint made with the paste. The paste should exhibit sufficient flexibility and resistance to cracking when bent. Additionally, examining the manufacturer's specifications or consulting with a materials engineer can provide more information on the ductility of the brazing paste.

Among the substances listed, iron (Fe) would have the greatest ductility. Ductility refers to the ability of a material to deform under tensile stress, and metals like iron are known for their malleability and ductility. In contrast, compounds like NaCl (sodium chloride) and SiO2 (silicon dioxide) are brittle and do not exhibit significant ductility. Carbon in the form of graphite (C(s)) has some ductility, but it is generally less ductile than iron.

Fe(s) because iron is a metal, and even if its not, this is the right answer;)
Malleability and ductility are characteristic of substances with metallic bonds, such as metals. These types of substances have a structure that allows their atoms to slide past each other easily, making them able to be hammered into thin sheets (malleability) or stretched into wires (ductility) without breaking.

Gold is known to have the greatest ductility among metals, allowing it to be drawn into extremely thin wires without breaking. Its ability to withstand deformation without fracturing makes it highly prized in various applications, including electronics and jewelry. Silver and copper also exhibit high ductility, but gold surpasses them in this property.
Substances that are brittle or lack ductility, such as glass, ceramics, and some types of polymers, are not malleable. These materials tend to fracture rather than deform when subjected to forces that would require malleability.
There may be other substances more ductile but Gold is the most ductile element.
