Valence electrons |
The electrons in the outermost energy level of atoms. Only includes the s and p orbitals. These electrons interact with other atoms to form bonds. Usually atoms are "happiest" with 8 valence electrons. |
|
|
Electronegativity |
The tendancy of an atom to "attract" or "take" electrons from other atoms. |
|
|
Duet Rule |
H and He are the only atoms that are "happy" with two instead of eight valence electrons. |
|
|
Octet Rule |
Atoms are "happiest" with the noble gas configuration, having eight valence electrons. |
|
|
Resonsance |
When there are more than one correct predicted molecular shapes. |
|
|
Lone Pair |
An unbonded pair of electrons. |
|
|
VSEPR Geometry |
Valence Shell Electron Pair Repulsion. Model that can predict molecular shape due to the repulsion and interaction of electrons. |
|
|
Dipole Moment |
Measure of polarity in a bond, has a partial positive and partial negative end. |
|
|
Covalent Bond |
Bond where electrons share electrons between atoms with very little or no difference (0-0.4) in electronagativity between bonded atoms. Include non-polar covalent |
|
|
Polar Covalent Bond |
Bond where electrons share electrons between atoms with some difference (0.4-1.7) in electronegativity between bonded atoms. |
|
|
Ionic Bond |
Bond where electrons share electrons between atoms with large difference ( >1.7) in electronegativity between bonded atoms. |
