|
Atomic radius
|
Atomic radius decreases as we move from left to right across periodic table
Atomic radius increases as we move from up to down due to increased shielding. |
|
|
Ionic radius
|
cation<neutral<anion
|
|
|
Ionization Energy
|
Amount of energy needed to remove least tightly bound e'n from an isolated atom
Ionization energy increases as you move from left to right or up a group |
|
|
Electronegativity
|
Measure of atoms ability to pull e's to itself when its froming covalent bond.
e-ty increases when you go from left to right and decreases when you go down group |
|
|
Covalent bond
|
Bond that forms when there is sharing of unpaired valence e's
|
|
|
Formal Charge
|
# of valence e's - # of unshared e's - 1/2 # of shareed e's.
|
|
|
Polar bond
|
Bond where e'n density between two atoms is uneven
|
|
|
Ionic Bond
|
Electrostatic attraction between cation and anion.(NaCl). Look for biggest e-ty difference.
|
|
|
Intermolecular forces
|
weak interactions between neutral molecules
|
|
|
Hydrogen bonding
|
FON
strongest interaction |
