Yes, lead iodide (PbI2) is a naturally occurring mineral known as iodargyrite. It is a rare mineral found in some mineral deposits, but it is more commonly synthesized for various industrial applications.
PBI2, or lead(II) iodide, consists of one lead (Pb) atom and two iodine (I) atoms. Therefore, there are a total of three atoms in one formula unit of PBI2.
This is a solid.
Formula: PbI2
The spectator ions in this precipitation equation are K+ and NO3-. The non-spectator ions are Pb2+ and I-. They combine to form the precipitate PbI2.
In the English language this reaction is called counter-ion exchange double displacement reaction.
Lead(II) iodide (PbI2) is typically a yellow colored solid.
Formula: PbI2
The oxidation number of lead (Pb) in PbI2 is +2. Iodine (I) typically has an oxidation number of -1 in compounds. Since there are two iodine atoms in PbI2, the total negative charge contributed by iodine is -2. This balances with the +2 charge of lead to make PbI2 neutral.
Pb(NO3)2(aq) + 2KI)aq) = 2KNO3(aq)+ PbI2(s) PbI2 is a yellow coloured solid and will precipitate out of the solution.
The balanced equation for lead iodide is: PbI2 (s) ↔ Pb2+ (aq) + 2I- (aq)
Formula: PbI2

This is a solid.
PbI2 is commonly known as Lead(II) Iodide. It is also sometimes called plumbous iodide from the Latin root plumbum, which means lead.
