<p>Is it really that necessary to study the most of the numbers in the electron distribution ? Is it going to appear on the test often?</p>
<p>You know like 1s2 2s2 2p6.... all that stuff.</p>
<p>Yes, you are often asked questions that involve electron configurations.</p>
<p>So it’s necessary to the order of the numbers and letters? mmkays then. Thanks.</p>
<p>Well you don’t need to know the exact numbers by memorization really. Just think of it based off of the periodic table. Also, you should prob know things about orbitals like shielding, etc.</p>
<p>Oops I forgot to put <em>memorize</em> on my last post</p>
<p>@whatdoyouthinkOh yes I know that part.</p>
<p>Mmkays thanks you guys :)</p>
