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

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

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

5. B. Covalent Bond
covalent bonds result in discrete molecules
NH3
H2O
Cl2

6. B. Covalent Bond Nonpolar Covalent Bond e- are shared equally
usually identical atoms

7. + - B. Covalent Bond Polar Covalent Bond
e- are shared unequally between 2 different atoms
results in partial opposite charges + -
