What characterizes an ionic bond?

Answer 1

An ionic bond is created when one atom gives up one or more electrons to another atom that accepts the electron(s). This creates a positive charge on the first atom and a negative charge on the second atom, which then electrically attract each other.

Answer 2

An ionic bond forms when one atom transfers electrons to another atom, resulting in the formation of oppositely charged ions that are held together by electrostatic attraction. This type of bonding typically occurs between metals and nonmetals.
