Final answer:
Lithium oxide contains an ionic bond, which happens when a metal like lithium donates an electron to a nonmetal such as oxygen, creating positively and negatively charged ions that attract each other(option a).
Step-by-step explanation:
The type of bonding represented in lithium oxide is a)ionic bonding.
This is because lithium is an alkali metal and oxide is a nonmetal oxide. According to the general rules of chemical bonding, when a metal and a nonmetal combine, they typically form an ionic compound due to the metal donating electrons to the nonmetal, resulting in the formation of positive and negative ions that attract each other. Lithium donates its single valence electron to oxygen, which needs two electrons to complete its octet, leading to the formation of Li+ and O2- ions. The strong electrostatic attraction between these oppositely charged ions constitutes the ionic bond in lithium oxide.
