None of the above

Detailed explanation-1: -An ionic bond is formed between a metal and a non-metal. Non-metals(-ve ion) are “stronger” than the metal(+ve ion) and can get electrons very easily from the metal. These two opposite ions attract each other and form the ionic bond.
Detailed explanation-2: -Metals tend to lose electrons to form cations and non-metals tend to gain electrons to form anions. So metals and non-metals form ionic bond by transferring electrons.
Detailed explanation-3: -A covalent bond is formed between two non-metals. The sharing of electron pair takes place between their atoms and a covalent bond is formed. Q. An ionic bond is formed when a non-metal and a metal form a bond by transferring electrons.
Detailed explanation-4: -An ionic bond is formed when an electron lost by one element is gained by another. In the case of two nonmetals, they both lose electrons so no electron transfer takes place. Thus an ionic bond can not be formed between two non-metals.
