No, urea is a nitrogen compound.
Iodine(I)
A crystal is a structure. A mineral is a material. A crystal is a regular arrangement of atoms, ions, or molecules in a solid. This regular internal structure leads to a geometrically regular external shape. Sodium chloride (common salt) crystals, for example, are cubic. A mineral is any element or compound, normally occurring naturally as crystals. Rocks consist of two or more minerals.
Nitrogen in its elemental form is covalently bonded. A free element cannot be ionically bonded.
CO(NH2)2 is the chemical formula for the organic compound urea. Urea is generated by the excretory systems of animals.
urea
Nitrogen is the primary element in urea [CO(NH2)2], along with carbon, oxygen, and hydrogen.
Simply put, no.
Iodine is a chemical element; not a mixture, not a compound.

Iodine(I)
urea, ammonia, amino acids, and many more
The chemical element of atomic number 53, a non-metallic element forming black crystals and a violet vapour.
Salt is a more cubic element than sugar
Copper sulfate crystals are a compound, not an element. The compound is formed by combining copper, sulfur, and oxygen atoms.
Pencil 'lead' does not contain crystals. It is a mixture of the element carbon (in the form of graphite) and clay.
Compound, crystal is not an element so obviously what it is made up of must be a compound <><><><> Crystals can be either an element (diamonds are carbon- and crystalline) or a compound (salt, sugar). Unsure of your meaning of "broken down".
