Yes it contains the lead (IV) ion.
lead IV chloride
The chemical formula of lead (IV) is PbF4.
Lead (IV) Oxide
The chemical formula of lead(IV) chromate is PbCrO4.
The lead ion is a cation, meaning that it has a positive charge. However, there are multiple lead cations, each with a different charge. These ions are lead (ii) and lead (iv), which have a 2+ and 4+ charge, respectively.
The formula for lead(IV) ion is Pb4+ and for nitrite ion is NO2-.
The Lead IV ion is Pb4+
lead (IV) ion is Pb4+ ion. Note that Pb4+ is never found as an ion- the (IV) is an oxidation number or oxidation state.
Lead IV is the 4+ ion formed by the element lead (Pb). Because Pb4+ is a positive ion it must be accompanied by a negative ion.
The IV in lead IV oxide means that the lead ion has a 4+ charge. The oxide ion has a 2- charge. The charges must cancel out to zero, so there are 2 oxide ions for every 1 lead IV ion, which is what the formula PbO2 shows.
Pb4+
Pb+4is known as lead(IV) in the stock system or a plumbic ion in the old naming system.
lead IV chloride
Lead (IV) ion
Lead iodide is not a correct name. Lead is a transition metal and can form more than one ion. The charge of the lead ion should be in the name. For example, lead(II) iodide, which would be PbI2. Lead(IV) iodide would be PbI4.
This would be an ionic compound. The lead (IV) ion is a metal, so it would be a cation (positive ion), and the numerals tell us it has a charge of 4+. The oxygen ion is a non-metal, so it would be an anion (negative ion) and it is in group 6A, so it would have a charge of 2-.The ionic compound needs to have a net charge of zero, so we would need two oxygen ions to balance out the charge of each lead (IV) ion.Therefore, the correct formula for lead (IV) oxide is PbO2.
The name of this compound is Pb(IV) sulfite or lead disulfite.
