Lead is a metal with an electronegativity of 2.33. This is very high for a metal. A simple prediction is that reactions with non metals of low electronegativity will form covalent bonds and with non metals of high electronegativity will form bonds which are ionic /covalent borderline. This is essentially what is found, for example, PbO is more ionic than PbS. PbS is essentially ionic but is also a semiconductor- so there is a covalent component to the bonding.
Lead has two oxidation states, lead(II) and lead(IV). the more stable state is lead(II). The first two ionization energies are similar to magnesium. Lead forms Pb2+ salts such as Pb(NO3)2 unlike most lead(II) salts this is soluble in water, and PbSO4 (found in car batteries), which is insoluble, and PbCO3 another insoluble salt called white lead when it was used in paints.
Lead(IV) compounds are not generally ionic - the ion Pb4+ would be highly polarising and would lead to covalent bonding, PbF4 is the most ionic - it is a high melting solid with a structure like SnF4. It is thermally unstable decomposing to produce fluorine.

What is the symbol and charge of a lead ion?
The symbol for a lead ion is Pb, and the charge can vary depending on the specific ion. Common lead ions include Pb^2+ and Pb^4+.
When Te is an ion in a compound what charge does it have?
When Te forms an ion in a compound, it typically has a charge of -2.
What charge is strontium?
Strontium typically forms a +2 charge.
What is the charge of Pb(NO3)2?
The charge of the lead ion in the compound lead phosphate, Pb3(PO4)2, is 2+.
What is the charge of magnesium when it forms an ion?
Magnesium as an atom has two valance electrons. To complete it's octet, it must lose two electrons. Losing two electrons will make Mg have 12 protons and 10 electrons therefore having a +2 charge.
Sodium forms an ion with a charge of what?
Sodium forms an ion with a charge of +1.
Ionic charge of lead?
Lead's ionic charge is variable. It is either +2 or +4 depending on the properties of the anions. These charges can also be referred to as "common ionic charge". Example of Pb+2 ionic charge: Lead(II) phosphide Pb+2 and P-3 Pb3P2 Example of Pb+4 ionic charge: Lead(IV) Sulfate Pb+4 and (SO4) -2 Pb2(SO4)4 simplified -> Pb(SO4)2
What ions make up the compound PbCl4?
The compound PbCl4 is made up of lead (Pb) ions and chloride (Cl-) ions. In this compound, the lead atom has a charge of +4, and each chloride ion has a charge of -1, so it forms four chloride ions to balance the charge of the lead ion.
Which element forms an ion with the same charge as the sulfate ion?
Calcium forms an ion with the same charge as the sulfate ion, which is 2-. This ion is written as Ca2+.
Which element forms an ion with the same charge as the ammonium ion?
The element hydrogen forms an ion with the same charge as the ammonium ion, which is +1. When hydrogen loses an electron, it becomes a hydrogen ion with a +1 charge, just like the ammonium ion.
What is the ion charge formed by oxygen?
Oxygen typically forms an ion with a charge of -2, called oxide ion.
What is the symbol and charge of a lead ion?
The symbol for a lead ion is Pb, and the charge can vary depending on the specific ion. Common lead ions include Pb^2+ and Pb^4+.
What is the symbol for lead ion?
The symbol for the lead ion with a charge of +2 is Pb2+.
What will the charge be when fluorine forms a ion?
When fluorine forms an ion, it gains one electron to achieve a stable electron configuration, becoming a fluoride ion with a charge of -1.
What is the charge on the lead ion in PbS2?
The charge on the lead ion (Pb) in PbS2 is +2. This is because each sulfur atom (S) has a charge of -2, and since there are two sulfur atoms for every lead atom in lead(IV) sulfide (PbS2), the lead ion must have a charge of +2 to balance out the charges in the compound.
What charge does Sr form when it forms and ion?
strontium is a metal, therefore it must form only positive ions.
What is the compound of Pbl4?
The compound PbI4 is lead (II) iodide, where the lead ion has a charge of +2 and the iodide ion has a charge of -1.
