1. Bond Angle- angle between the bonds connecting the atom in the molecule

2. Bond Energy- energy involved in forming or breaking a bond

3. Chemical Bond- strong attractive force between atoms or ions in a compound

4. Covalent Bond-nonionic chemical bond formed by shared electrons

5. Crystal Lattice- three-dimensional arrangement of cations and anions

6. Dipole- bond in which there are two separated, equal but opposite, charges

7. Double Covalent Bond- bond in which four electrons (two pairs) are shared by the bonding atoms

8. Electronegativity- measure of attraction an atom has for a shared pair of electrons

9. Electrostatic Attraction- the attraction between particles of opposite charge

10.Ionic Bond (*1.7)- chemical bond formed by electrostatic attraction between a cation and an anion

11.Nonpolar Covalent Bond (0.0)- bond in which electrons are equally shared by two nuclei

12.Octet Rule- rule based on assumption that atoms form bonds to achieve a noble gas electron configuration

13.Polar Covalent Bond- bond that has a Dipole

14.Tetrahedral- four-faced molecule

10. Trigonal Planar- molecule with three atoms at corners of a triangle and the central atom in the middle

11. Trigonal Pyramid- three- sided, pyramid- shaped molecule

12. Triple Covalent Bond- bond in which two atoms share three pairs of electrons
