Which best describes how an ionic bond forms?

A. One atom pulls an electron from another atom.

B. Two atoms both lose an electron.

C. Two molecules share an electron.

D. Two atoms share valence electrons

Answer: A. One atom pulls an electron from another atom.

Ionic bonding involves the transfer of electrons from one atom to another, resulting in the formation of positively charged ions (cations) and negatively charged ions (anions). This transfer occurs because one atom has a stronger attraction for electrons than the other, leading to the transfer of electrons from the less electronegative atom to the more electronegative atom.
