Answer 2

Answer:

This concept is taught horribly in high school chemistry. A lone Na atom is inherently more stable than a lone Na+ ion. The first ionization energy is always positive, meaning that for all atoms, lone atoms are more stable than lone ions.

However, Na+ ion can form meshes with other ions, forming ionic compound. There is an energy change associated with the formation of ionic compound. A Na+ ion in an ionic compound has less energy than an Na atom and is more stable.

Thus,

Energy of lone Na+ ion > energy of a lone Na atom > energy of a Na+ ion in an ionic compound
