<p>I just started studying for next week's chem SAT :( and was wondering how much we have to memorize? I know you're only given a periodic table and are expected to know solubility rules, but what about activity series, polyatomic ions, etc?</p>
<p>Bump Bump…!</p>
<p>You should know the trends in the periodic table. e.g. ionization energy, metallic/non-metallic, reactivity/stability, ionic radius. All of this stuff is intuitive anyway.</p>
<p>Activity series is not important. If you want to learn it anyway here is a mneomic to help you: Private Second Class MacZitl he can make some gun powder</p>
<p>Polyatomic ion, once again, not important. Just know the common ones provided in this table: [Polyatomic</a> ion - Wikipedia, the free encyclopedia](<a href=“http://en.wikipedia.org/wiki/Polyatomic_ion]Polyatomic”>Polyatomic ion - Wikipedia)</p>
<p>my score: 780 May 2011 test</p>
