Ionic bonds involve electrostatic forces between ions

Steps:

• Identify ionic bonding as the attraction between positive and negative ions formed by electron transfer.
• Review choices: A matches the bond's nature; B describes covalent bonds; C and D describe ion formation, not the bond.
• Eliminate B, C, D as they misstate the bond itself.
• Confirm A as the precise definition.

Why A is correct:

• Ionic bonds are defined as the electrostatic attraction between oppositely charged ions, per basic chemistry principles.

Why the others are wrong:

• B: Describes covalent bonding via electron sharing for octet stability.
• C: Explains electron transfer to form ions, a precursor to ionic bonds, not the bond.
• D: Same as C, with a phrasing error; focuses on transfer, not attraction.

Final answer: A
