A cation is any element with a positive charge. Lead most commonly forms an anion, which means it has a negative charge. But any element can have any charge, but only under certain condistions

Cation = a positive ion.
Therefore electron charge is 1+.
If more electrons are removed it will go: 2+, 3+, 4+. 5+....
The charge of the nucleus of a lead atom is 82. Atomic number of any element is the charge of the nucleus of that atom.
Pb10S10 The prefix deca in decasulfide means that there are 10 sulfide ions in the formula, each with a 2- charge. So the total negative charge is 10 x 2-, which equals 20-. To balance the total sulfide charge, you need enough lead II ions to equal 20+, so that means 10 lead II ions, which equals a charge of 20+. This is not really the correct way to name this compound. It should just simply be lead II sulfide, and the proper formula would be PbS, which, if you look at the ratio of lead to sulfide ions, which is 10:10, the formula for lead II decasulfide should be reduced to PbS.
2 or 4 just for fun, Tin also has a charge of 2 or 4. The names of lead are plumbous (2 charge) and plumbic ( 4 charge). You can also name it like lead (II). Read a textbook, your so ignorant.
Lead(II) fluoride (PbF2) is insoluble in water. This is because lead(II) compounds typically have low solubility in water due to the high charge density and larger size of the lead(II) ion.
Plumbous refers to Lead II. The II means it is in a +2 state. Therefore, this requires two Iodines as they have -1 charge. Therefore the formula is PbI2
Lead (II) Sulfite
