VSEPR Theory

Electron pairs in the valence shell stay as far apart as possible allowing prediction of molecular shapes.

2

Resonance Structure

Different arrangements of electrons of the compound having a geometrical structure.

3

Unshared Pair

A non-bonding pair of electrons.

4

Lewis Structure

Diagram using dots to represent electrons.

5

Valence Electrons

Number of electrons in the outermost energy level.

6

Dipole

Molocule with both a positive and negative region.

7

Covelent Bonds

When atoms share one or more pairs of electrons.

8

Molecular Orbital

The probable region of an electrons location around a molecule.

9

Polar Compound

A molecule where the shared electrons are held more closely by one atom yielding a positive and negative end.

10

Ionic Bond

The bond between a cation and an anion to form a compund.

11

Hydrogen Bond

Intermolecular attraction between a H of a molecule and a charged region.

12

Double Bond

Two atoms that share four electrons.
