What does paramagnetic and diamagnetic describe in regards to an atom?
|
They describe whether or not the atoms valence orbital(s) is filled or unfilled
|
|
Define isoelectric. give an example.
|
Atoms, ions, or molecules with the same # of electrons. One of which must be an ion. I.e. 02- and Na+
|
|
What is the difference between Hund's rule and Aufbau's principle?
|
Hund's rule states that there must be one electron in each orbital of a given energy level before any pairs of electrons are formed. Aufbau's principle just states that each energy level must be filled prior to the next.
|
|
What three common rules can be followed when dealing with solubility.
|
1. all salts of alkali metals are water soluble.
2. all nitrates are water soluble. 3. all salts of the ammonium ion (NH4+) are water soluble. |
|
What molecules are insoluble most of the time and in what cases do they become soluble?
|
Carbonates (CO32-), Phosphates (PO43-), Sulfides (S2-) and Sulfites (SO32-) are always insoluble.
