Explanation:
Ionic compound are chemical compound held by electrostatic forces known as ionic bonding. Ionic compound, their is transfer of electron. One atom of element lose electron while the other atom gain electron. The ions involve in bonding are known as cations and anions.
The cations loses electron to become positively charged while the anion receive electron to become negatively charged. An ionic compound possess an anion and a cations. The electronegativity difference between the atom that go into bonding is widely different.
The best option is the bonding between lithium (cations) and chlorine(anions) and potassium(cations) and oxygen(anions).
The bonding is usually between a metal and a non metal.
Li + and Cl- → LiCl
K+ and O2- → K2O
