An ionic bond can be formed when one or more electrons are:

A) Equally shared between two atoms
B) Unequally shared by two atoms
C) Transferred from the nucleus of one atom to the nucleus of another atom
D) Transferred from the valence shell of one atom to the valence shell of another atom

D - for example, Potassium has 1 electron on its outer shell, whilst Chlorine has 7 electrons on its outer shell. Potassium loses one electron to Chlorine so that each of them have a full outer shell. This would form Potassium Chloride.

Ionic bonds form when electrons are transferred from one atom to another, creating charged ions. The atom that loses electrons becomes a positively charged cation, while the atom that gains electrons becomes a negatively charged anion. Therefore, the correct answer to the question is D) Transferred from the valence shell of one atom to the valence shell of another atom.
