Questions and Answers

In the process of forming an ionic bond between sodium and chlorine, what happens to the electron configuration of sodium?

Sodium's inner shell loses an electron to achieve a stable configuration

Sodium loses its single outer electron to achieve a stable configuration (correct)

Sodium gains an electron to achieve a full outer shell

Sodium's outer shell remains unchanged, and it shares an electron with chlorine

What is the fundamental reason for the formation of an ionic bond between sodium and chlorine?

To achieve a balanced distribution of protons and neutrons

To create a covalent bond between the two atoms

To satisfy the octet rule and achieve a stable electron configuration (correct)

To transfer energy from sodium to chlorine

Which of the following statements accurately describes the structure of an atom?
