Both crystalline and brittle mean to break easily - fine china, thin glass, etc.
Potassium iodide is a brittle crystalline solid at room temperature.
Yes, germanium is considered brittle. It is a rigid, lustrous, and grayish-white metalloid with a crystalline structure that tends to fracture easily under stress.
no, it is less ductile and malleable than is glass.
it is an amorphous solid
No, silicon is a brittle and hard crystalline solid at room temperature. It is not malleable and does not exhibit the properties of metals like ductility and malleability.
Potassium iodide is a brittle crystalline solid at room temperature.
Glass is an example of a solid that is amorphous (lacks a regular crystalline structure) and brittle (easily breaks or shatters when subjected to stress).
ionic substances tend to be crystalline and brittle- although they are often encounterd as fine powders so these physical characteristics are not apparent
peanut brittle
yes selenium is brittle, it it is struck it will usually crumble.
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.
Yes, germanium is considered brittle. It is a rigid, lustrous, and grayish-white metalloid with a crystalline structure that tends to fracture easily under stress.
Iodine itself is not brittle, as it is a non-metallic element that is usually found as a crystalline solid. However, the crystalline structure of iodine can be fragile if subjected to pressure or mechanical stress.
silicon is actually quite ductile as it is a metal
no, it is less ductile and malleable than is glass.
it is an amorphous solid
