Lead (II) iodide (PbI2) is ionic. Lead (Pb) is a metal and iodine (I) is a nonmetal, so they form an ionic bond by transferring electrons. In this compound, lead forms a 2+ cation and iodine forms a 1- anion, resulting in an overall neutral compound.
Lead can form both ionic and covalent compounds. In its ionic form, lead typically forms a 2+ cation, such as in lead(II) chloride (PbCl2). In its covalent form, lead can form covalent compounds with nonmetals, such as lead(IV) oxide (PbO2).
Lead nitrate is an ionic compound. Lead has a 2+ charge and nitrate has a 1- charge, so they attract each other through ionic bonds, where electrons are transferred from lead to nitrate.
PbO2 is a covalent compound. It contains lead (Pb) and oxygen (O) atoms bonded together through covalent bonds, where electrons are shared between the atoms.
The systematic name of this compound is Lead(II) Sulfate(VI), and the common name is lead sulfate.
lead nitrate(Pb(NO3)2 + potassium iodide(KI) = lead iodide(PbI) + potassium nitrate (KNO3)

Lead oxide typically exhibits a combination of ionic and covalent bonding. In lead(II) oxide (PbO), the bonding is primarily ionic between the lead(II) cation and oxide anion. In lead(IV) oxide (PbO2), there is a mixture of covalent and ionic bonding due to the presence of the peroxide (O2^2-) anion.
PbO2 is a covalent compound. It contains lead (Pb) and oxygen (O) atoms bonded together through covalent bonds, where electrons are shared between the atoms.
The systematic name of this compound is Lead(II) Sulfate(VI), and the common name is lead sulfate.
lead nitrate(Pb(NO3)2 + potassium iodide(KI) = lead iodide(PbI) + potassium nitrate (KNO3)
Pb(NO3)2 + 2KI -> PbI2 + 2KNO3.
FeI2 is Iron (II) iodide, an ionic compound composed of iron with a +2 charge and iodide with a -1 charge.
Covalent; 2 non-metals bonded are covalent; a metal and a non-metal are ionic
Lead(II) nitrate (Pb(NO3)2) and potassium iodide (KI) are ionic compounds that are typically found as solids at room temperature. When mixed together in an aqueous solution, they can form a precipitate of lead(II) iodide (PbI2), which is also a solid.
When potassium iodide is mixed with lead nitrate, a double displacement reaction occurs. The products formed are lead iodide and potassium nitrate. Lead iodide is a yellow precipitate that forms during the reaction.
Br2 is a covalent compound. It consists of two bromine atoms sharing electrons to form a covalent bond.
