Concept explainers
Interpretation:
The compound formed between elements Zinc and Oxygen needs to be explained.
Concept introduction:
Molecules are bound together by different types of bonds namely ionic and covalent. Ionic bonds are formed when there is complete transfer of electrons from one atom to another. These atoms either lose or gain electrons to become negatively or positively charged ions. The forces of attraction between these ions causes the ionic bond formation.

Answer to Problem 69A
The compound formed between elements Zinc and Oxygen is
Explanation of Solution
Ionic bonds involve the transfer of electrons from one atom to the other. The metal atoms, an electrons donor, loses electrons to form a positively charged ion while the non-metal atoms, electron acceptor, gains electrons to form negatively charged ions. During the process of donating or gaining electrons, the atoms follow octet rule to attain a stable noble gas configuration. Therefore, the charges on the anion and cation depends on the electrons lost or gained giving net charge of zero.
Zinc has
Oxygen has atomic number as 8 with electronic configuration as
The compound between Zinc and oxygen is Zinc oxide in which the anion is
