An ionic bond is formed when hints hint 1. the key to the answer is the word "ion." an ionic bond is formed when one atom transfers an electron to another atom atoms are subjected to radioactive isotopes both atoms are equally attractive to electrons both atoms are nonpolar both atoms are electrically neutral

Answer : An ionic bond is formed when one atom transfers an electron to another atom.

Ionic bond is formed when one or more electrons from the valence shell of an atom (electropositive metal ) are completely transferred to the valence shell of another atom (electronegative non-metal).

Ionic bonds form when one atom gives up one or more electrons to another atom. It is the complete transfer of valence electron(s) between oppositely charged atoms

For example NaCl (sodium chloride ) is an ionic bond, in which valence electron from Na gets completely transferred to the valence shell of Cl and ionic bond is formed between opposite ions that is Na (positive) and Cl (negative).

Note : Ionic bond is formed between metal (electropositive element) and non-metal(electronegative element).
