<p>The highest ionization energy question was Cl.</p>
<p>Princeton Review’s Question from the 2011-2012 book</p>
<p>Identify the element with the greatest first ionization energy.</p>
<p>A. Ce
B. C
C. Cl
D. Ca
E. Cs</p>
<p>Answer: B</p>
<p>There was another question that talked about the lowest ionization energy of the period…?</p>
<p>i think it was highest electronegativity and that was Cl</p>
<p>Aren’t we not allowed to discuss the questions? 0:</p>
<p>violinplayer,</p>
<p>Yes! I remembered that question and picked carbon. Lemme look it up…</p>
<p>EDIT: Cl is 1251.1 kJ mol-1, C is 1086.5 kJ mol-1. You have GOT to be kidding me.</p>
<p>wait. the test asked for lowest first ionization energy.
which was cs (cesium)</p>
<p>@Ilyana: that was a princeton review question</p>
<p>Hmm, Wikipedia disagrees</p>
<p>C: 1st: 1086.5 kJ·mol−1
Cl: 1st: 1251.2 kJ·mol−1</p>
<p>how do u guys not know that Cl is the strongest element on the table?</p>
<p>I think it was electronegativity…if it was actually ionization energy, then i can understand why it’s carbon. Ionization energy can be quite the tricky one…</p>
<p>So far i think i may have 1 or 2 wrong. I didn’t omit any but my iffy ones turned out all right.</p>
<p>Does anyone remember the one regarding equilibrium, which gave 3 options as to which statements are true? Options:</p>
<ol>
<li>The observable properties are constant during equilibrium.</li>
<li>Forward and reverse rates are equal.</li>
<li>Catalyst will result in more product at equilibrium.</li>
</ol>
<p>I put 1 & 2, the observable properties such as pH and concentrations are constant at equilibrium, and forward and reverse rates are equal (since the amounts of product and reactant are constant). The 3rd one is false.</p>
<p>… PR is wrong? QQ</p>
<p>No its ionization energy</p>
<p>I know I picked Cs (lowest ionization energy) for one and Cl (something to do with S vs Cl I think) for another @_@</p>
<p>concretepencil,</p>
<p>It’s not. Fluorine has the highest electronegativity, and we’re talking about ionization energy. I chose Cl on the PR practice test (and thought I’d gotten it wrong, per the book) and then picked carbon on the real test. Didn’t think to double-check the book.</p>
<p>Gah.</p>
<p>I picked Cs too.</p>
<p>Princeton says its Carbon and its no typo.</p>
<p>Also consensus on the linear CO2 one?</p>
<p>Immadinosaur, no it didn’t, but you must be confusing it with some other question that was referring to lowest of some property.</p>
<p>Does anyone remember the one in which you had to balance __O2…?</p>
<p>@violinplayer I’m afraid so…</p>
<p>@llazar I picked I and II as well. III is completely incorrect (but I thought the III option was “concentrations are equal at equilibrium” or something like that)</p>
<p>@Daisie: Flourine was not an option for the question, but if it were, that would be the answer.</p>
<p>Chewydog, that’s probably it, my memory is fuzzy. This ionization energy question is messing with me right now, if i read lowest as highest…:(</p>
