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 forms when an ion has a 1 charge?
cation
What is the charge of Pb(NO3)2?
The charge of the lead ion in the compound lead phosphate, Pb3(PO4)2, is 2+.
How many electrons does an atom of lead have if it is positively charged?
Lead forms the Pb2+ ion, as lead has an atomic number of 82, the Pb2+ ion has 80 electrons in total
What is the charge on barium ion?
Barium forms a +2 charge, along with all other group 2 metals.
What type of ion forms when atom lose electrons?
Losing an ion creates a positive charge. This forms a positive ion.
What is the ionic charge of lead?
Pb is in the p block. It forms Pb+2 ion.
What is the charge on the monatomic ion that calcium forms in its compounds?
Calcium forms a 2+ ion.
Sodium forms an ion with a charge of what?
Sodium ions have a charge of 1+
Which element forms an ion with the same charge as the ammonium ion?
potassium
What forms when an ion has a 1 charge?
cation
What is the charge on the lead ion in PbS2?
Lead being a transition metal has two possible charges: +2 or +4.
Which element forms an ion with the same charge as the sulfate ion?
The sulfate ion is SO42-. Elements in group 16 form anions with a charge of 2-, for example oxygen forms the oxide, O2- anion.
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 most likely charge on an ion when hydrogen forms an ion?
Most likely, hydrogen will form a cation, meaning it will have a positive charge of +1
Why is lead IV oxide PbO2?
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.
What is the Difference between lead and azide?
Lead is a metal. It is the 82nd element. It forms the Pb2+ and Pb4+ ions. Azide is a negative ion with the formula N3-. It cannot occur on its own , it needs some positive ion to balance its charge (example the sodium ion Na+ to form sodium azide, NaN3). Compounds with this ion, called azides, are explosive.
What is the common charge in potassium when it forms an ion?
plus one, always!
