E. A noble gas configuration is formed for each element or ion.

Explanation:

An ionic bond is an electrostatic force that holds ions together in an ionic compound.

This ionic bonding is produced between a low electronegativity element, which gives one or more electrons transforming into a cation. A high electronegativity element receives one or more electrons transforming into an anion.

By the Lewis-octet rule, when elements join to form a compound they acquire the noble gas configuration of the closest noble gas.

For example, magnesium loses two electrons to form Mg²⁺, and its configuration is the same as that of neon (Ne) gas.
