The three forms of lead are 1) Metallic lead 2) Inorganic lead and lead compounds (or lead salts) 3) Organic lead (containing carbon)
No, lead does not have a crystalline structure. It has a close-packed hexagonal structure in its solid state.
as with all metals, lead is a polycrystalline solid.

The mineral you are referring to is galena. Galena is a dense, metallic mineral that is the primary ore of lead, composed of lead sulfide (PbS). It often appears in a crystalline form and is known for its high density and metallic luster.

An anglesite is a crystalline mineral form of lead sulphate, formed by the weathering of galena.
A typical lead pencil does not actually contain lead. The "lead" in a pencil is made of graphite, which is a crystalline form of carbon. Therefore, there is 0% lead in a lead pencil.
No, lead does not have a crystalline structure. It has a close-packed hexagonal structure in its solid state.
as with all metals, lead is a polycrystalline solid.
Salt is a crystalline solid in its natural form.
Corundum is a crystalline form. This crystalline form is made up of aluminium oxide.
The crystalline form of water is called ice. It does not form at room temperature.
Not all crystalline materials are semiconductors.
When you mix two different solutions. You get crystalline solution.
Both diamonds and pencil lead are made out of the element carbon. The difference lies in their structures: diamonds have a crystal lattice structure, while pencil lead is made up of layers of graphite.
Pencil "lead" is not actually lead; it is made from a mineral called graphite. Graphite is a crystalline form of carbon that is naturally occurring and meets the criteria to be classified as a mineral based on its chemical composition and physical properties.
Lead is not used in pencils. Instead, pencils contain graphite, which is a crystalline form of carbon that leaves a gray mark on paper when used. The term "lead pencil" is a misnomer that dates back to when graphite was mistaken for a form of lead.
