In ionic bonding
a. the electrons are shared between the atoms.
b. at least two of the above statements are correct.
c. the bonding that occurs is usually between two nonmetal atoms.
d. the process of forming an ionic bond is highly endothermic overall.
e. a noble gas configuration is formed for each element or ion.

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.

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.
