<p>Another question I’d like to add - are we expected to know the order of the elements for decay problems? It’s easy to remember for elements toward the beginning but how are you supposed to remember those in the 80s and 90s?</p>
<p>You don’t have to remember them. You’ll get the number of protons AND the name of the element it corresponds to, no answer choices will ask you to know how many protons this specific element has</p>
