Q
Solubility Rules
A
Group 1 + Ammonium Ions are soluble.
All nitrates, acetates, and chlorates are soluble.
2
Q
Bonding
A
Ionization Energy is directly proportional to Electronegativity.
* IE ~ Energy required to remove electron (First ~ Outermost)
* EN ~ Ability of element to attract electrons
* Atomic Radius is inversly proportional to both.
Nuclear shielding causes a decrease in ionization energy when energy levels increase.
More IMF ∝ More Melting and Boiling
Nonpolar implies LDF
Polarity ∝ IMF
More EN Difference ∝ More Polarity .
Ionic will always be more polar than covalent.
More Molecular Size ∝ More LDF
