Answer;
The possible choice is a non-metal that lacks an octet configuration.
Explanation;
- Ionic bond is a type of bond that is formed between a metal and a non metal. This type of bond occurs as a result of transfer of electrons where an atom of a metal looses electrons and that of a non metal gains electrons. Consequently, the atoms involved attain a stable configuration, where one becomes a cation and the other becomes an anion.
- In this case, Sodium and a non metal that does not have an octet configuration will form an ionic bond because sodium is a metal that requires to loose one electron to form a stable configuration, while a non metal would require to gain electron(s) to attain a stable configuration.
