What is the predicted ionic charge for a Pb ion?

Question

Quizplus · Accepted Answer

Pb (lead) is a metal located in group 14 of the periodic table, meaning it has 4 valence electrons. It can either lose or share these electrons. However, since losing 4 electrons would require a lot of energy, it is more likely that lead will lose 2 electrons to form a 2+ ion, or lose all 4 electrons to form a 4+ ion. The most stable ion is the one with a noble gas electron configuration, which for lead is achieved by losing all 4 valence electrons to form a 4+ ion. Therefore, the predicted ionic charge for a Pb ion is 4+.
