In the formation of the ionic compound CaBr₂ the number of electrons transferred from one Ca atom to two Br atoms, per formula unit, is ________.

Question

Quizplus · Accepted Answer

Calcium (Ca) has 2 electrons in its outer shell and tends to lose both to achieve a stable electronic arrangement, forming a Ca^2+ ion. Each bromine (Br) atom can accept one electron to form a Br^- ion. Therefore, one Ca atom transfers a total of 2 electrons to two Br atoms to form CaBr2.
