Which of the following best represents the bonding for CaO?

Question

Quizplus · Accepted Answer

CaO is an ionic compound composed of a metal (Ca) and a non-metal (O). This type of bonding is referred to as ionic bonding. In ionic bonding, electrons are transferred from the metal to the non-metal resulting in the formation of ions with opposite charges. In this case, Ca loses 2 electrons to become Ca2+ while O gains 2 electrons to become O2-. The ions are then attracted to each other by electrostatic forces to form the ionic compound. Choice C represents this by showing the transfer of electrons from Ca to O and the resulting formation of Ca2+ and O2- ions. Choice A represents covalent bonding which involves the sharing of electrons between atoms of non-metals.
