Calcium chloride, CaCl₂, is an ionic compound in which A) one chlorine atom transferred an electron to the other chlorine atom. B) each chlorine atom has lost electrons. C) calcium has two extra electrons in its innermost shell. D) calcium has gained two electrons. E) calcium has lost two electrons.

Question

Quizplus · Accepted Answer

Calcium chloride is an ionic compound, which means that there is a transfer of electrons between the atoms involved. In this case, the calcium atom has a tendency to lose its two outermost electrons, while the chlorine atoms have a tendency to gain one electron each. Therefore, the correct answer is E, as calcium has lost two electrons to fulfill the octet rule and become a cation with a 2+ charge, while the chlorine atoms have gained one electron each to become anions with a 1- charge.
