Ch. 11 - Chemical Bonds II. Kinds of Chemical Bonds(p.304-308) Ionic Bond Covalent Bond Comparison Chart
A. Ionic Bond • Attraction between 2 oppositely charged ions • Ions - charged atoms • formed by transferring e-from a metal to a nonmetal
NaCl A. Ionic Bond • ions form a 3-D crystal lattice
B. Covalent Bond • Attraction between neutral atoms • formed by sharing e- between two nonmetals
Cl2 H2O NH3 B. Covalent Bond • covalent bonds result in discrete molecules
B. Covalent Bond • Nonpolar Covalent Bond • e- are shared equally • usually identical atoms
- + B. Covalent Bond • Polar Covalent Bond • e- are shared unequally between 2 different atoms • results in partial opposite charges
B. Covalent Bond • Nonpolar • Polar • Ionic View Bonding Animations.
