A. Ionic Bond
Attraction between 2 oppositely charged ions• Ions - charged atoms• formed by
transferring e-
from a metal to a nonmetal

A. Ionic Bond
• ions form a 3-D crystal lattice

B. Covalent Bond
Attraction between neutral atoms• formed by sharing e- between two
nonmetals

B. Covalent Bond
• covalent bonds result in discrete molecules

Nonpolar Covalent Bond• e- are shared equally
• usually identical atoms

Polar Covalent Bond• e- are shared unequally between 2 different
atoms
• results in partial opposite charges
