Metalloids are all malleable, but some are more malleable than others. Some have a brittle crystalline structure that prevent them from being malleable enough for many practical applications.
Brittle because it contains impurities such as carbon and sulfur. The structure of the molecules in iron, particularly when cast, is such that it is almost crystalline in nature and breaks easily. The addition of carbon and other metals into the mix gives you more malleable compounds that are less brittle and can convert it to what we refer to as steel.
Aluminum is a crystalline solid with an FCC structure
Camphor is a crystalline substance.
Yes! it is brittle
Both crystalline and brittle mean to break easily - fine china, thin glass, etc.
Iodine is malleable when it is in crystalline form.
It is an amorphous solid. The sugar in peanut brittle is melted and then is cooled too fast for the crystalline structure to properly reform, making it irregular.
Glass is an example of an amorphous solid or non-crystalline material. Glass is typically characterized to be brittle and optically transparent.
Germanium IS the scientific name for an element that is brittle, crystalline, gray-white, and metalloid.
is magnesium brittle or can it be bent and shaped?
Antimony is a metalloid because it possesses qualities of metals and non-metals such as: a hard, extremely brittle, lustrous, silver-white, crystalline material.
ionic substances tend to be crystalline and brittle- although they are often encounterd as fine powders so these physical characteristics are not apparent
Bromine is a liquid at room temperature. Cooled below its freezing point, bromine would probably be a brittle crystalline solid much like iodine.
Metalloids
A boron is brown colored, soft-brittle, and is either amorphous or crystalline. It can also be red or gray color too depending on its form. It is mainly removed from borax or kernite.
Technetium is a crystalline, transition metal.
