Ionic vs. Covalent Bonding

Ionic vs. Covalent Bonding. 9/11/08. Why bond? Most atoms are not stable by themselves. A chemical bond provides stability for both atoms involved by lowering the potential energy of both atoms.

Ionic Bonding

Ionic Bonding. TRANSFER OF ELECTRONS. Ionic bonds result from the electrical attraction between cations and anions. Involve the transfer of electrons. Ionic bonds form between a metal and a nonmetal. The metal always transfers electrons to the nonmetal.

Implications of differences in structure

Implications of differences in structure. Ionic solids Conduct electricity in solution (not as solid) Ions break free from electrical attraction when in solution and are free to migrate and carry the current.
