If you mix a typical iodine ion (I, atomic no. = 53)with a typical barium ion (Ba, atomic no. = 56), what compound is formed?

Question

Quizplus · Accepted Answer

Barium (Ba) has a +2 charge as it typically loses two electrons to achieve a stable electron configuration, while iodine (I) typically gains one electron to form an ion with a -1 charge. To balance the charges, two iodine ions are needed for every barium ion, forming BaI₂.
