Question

question 1 of 10
an ionic bond is most accurately described as forming through:
the sharing of electron pairs between two nonmetal atoms.
the transfer of electrons from one atom (typically a metal) to another atom (typically a nonmetal), resulting in oppositely charged ions.
the delocalization of electrons among many metal atoms.

Explanation:

• For the first option, sharing of electron pairs between two non - metal atoms is characteristic of covalent bonds, not ionic bonds.
• For the second option, ionic bonds are formed when electrons are transferred from a metal atom (which has a low ionization energy) to a non - metal atom (which has a high electron - affinity). This transfer results in the formation of positively charged cations (from metals) and negatively charged anions (from non - metals), and these oppositely charged ions are held together by electrostatic forces.
• For the third option, delocalization of electrons among many metal atoms is the basis of metallic bonding.

Answer:

The transfer of electrons from one atom (typically a metal) to another atom (typically a nonmetal), resulting in oppositely charged ions.
