Final answer:
The charge of the ion typically formed by lead is 2+ when it loses 4 electrons.
Step-by-step explanation:
The charge of an ion typically formed by each element can be predicted using the periodic table. Moving from left to right on the periodic table, main-group elements tend to form cations (positively charged ions) with a charge equal to their group number. For example, group 1 elements form 1+ ions, group 2 elements form 2+ ions, and so on.
However, it's important to note that in the case of lead (Pb), it is a transition metal and does not follow this trend. Lead typically forms a 2+ ion by losing 4 electrons. This can be inferred by understanding the electronic configuration of lead, where it loses its two outermost ns^2 electrons to achieve a stable half-filled d subshell.
Therefore, the charge of the ion typically formed by lead is 2+ when it loses 4 electrons.
