---|---|---|---|---|---|
Bond | Force that holds groups of 2 or more atoms together. They work as an unit
🗑
|
||||
Bond Energy | Energy needed to break the bond
🗑
|
||||
* Ionic Bonding | Attraction of opposites (anions and cations)
🗑
|
||||
Ionic Compound | Metal attracted to non metal
🗑
|
||||
* Covalent Bonding | Electrons are shared by nuclei to form molecules. Ex H molecule
🗑
|
||||
* Polar Covalent Bond | Electrons are not shared equally
Atoms are not so different that e- are completely transferred but are different enough to share unequaly. Ex HF
🗑
|
||||
* Electronegativity | Ability of an atom in a molecule to attract electrons in a chemical bond.
🗑
|
||||
Dipole moment | Molecule that has a center of + & a center of - charge
🗑
|
||||
Principle | All atoms of stable chemical compounds of rep elements achieve a noble gas electron configuration.
🗑
|
||||
* Lewis Structure | shows the bonds between atoms.
1. Add all valence e-
2. Divide by 2 (pairs)
3. Surround central atom with 4 e- pair
4. Remaining e- complete the octet
5. Two exceptions H (only needs 2 e-/ B only needs 6 e-)
🗑
|
||||
Duet Rule | Sharing of 2 e-
🗑
|
||||
* Octec Rule | (one 2s & three 2p orbitals) e- are needed to fill the orbitals
🗑
|
||||
* Bonding electrons | Electron pairs are shared by atoms
🗑
|
||||
* Non bonding electrons | The 3 other pairs of e- that are not shared
🗑
|
||||
* Single Bond | 2 atoms share 1 e- pair
🗑
|
||||
Double Bond | 2 atoms share 2 e- pairs
🗑
|
||||
Triple Bond | 2 atoms share 3 e- pairs
🗑
|
||||
* Resonance | More than one Lewis structure can be drawn for a molecule.
🗑
|
||||
* Molecular Structure | 3D arrangement of atoms around a central atom due to electron repulsion
🗑
|
||||
* Linear Structure | All atoms in a line. Ex CO2 180 bond angles
🗑
|
||||
* Triagonal Planar Structure | 120 bond angles
🗑
|
||||
* Tetrahedral Structure | Four identical triangular faces (4 bonding pairs and the atoms are repelled to the 4 corners)
🗑
|
||||
* Valence shell electron pair repulsion (VSEPR)model | Electron pairs surrounding an atom repel each other
🗑
|
||||
* Trigonal Pyramid | One side is different from the other 3
(3 bonding pairs and 1 nonbonding pair)
🗑
|
||||
* Cation | Positively charged (loses e-)
🗑
|
||||
* Anion | Negatively charged (gains e-)
🗑
|
||||
* Non Polar Covalent Bond | Bond is not polarized. Difference is less than 0.5 (electronegative difference)
🗑
|
||||
* Delta notation | Used to state the charge on polar bonds
🗑
|
||||
* Coordinate Covalent Bond | One atom gives a lone pair of e- to another atom
🗑
|
||||
* Hydrogen Bond | Intermolecular attraction. Like H attracted to O in a water molecule
🗑
|
||||
* Electron dot formula | Symbol of an element surrounded by its valence e-
🗑
|
||||
* Electron pair geometry | Shows the arrangement of bonding and nonbonding e- pairs around the central atom
🗑
|
||||
* Bond Lenght | The distance bt the 2 atoms is smaller than the sum of ther atomic radii
🗑
|
||||
* Bond energy | Energy needed to break a covalent bond
🗑
|
||||
* Structural Formula | Uses dashes to show bonding
🗑
